This year we achieved that objective and so much more! Things started with a bang in January when the Ministry of Natural Resources formally announced their acceptance of the new wild-take policy. Although we did not get everything we asked for, this was a huge step forward for falconry and represented the culmination of years and years of effort by the Club on many levels. After the announcement, I had the very pleasant task of writing thank you letters to the current and former Ministers of Natural Resources and the MNR staff that were instrumental in developing the policy and guiding it through the process. Compared to the whirlwind of activity in 2011 surrounding the EBR posting I thought things would settle down quickly, but something totally unexpected happened! After years of caution regarding wild take, it seems the MNR became very excited about this new program and its implications. We were contacted about doing a falconry cover for the Hunting Regulations, which by now I am sure you have all seen. Shortly afterward we were asked to help staff a large falconry display in the MNR’s booth at the Toronto Sportsmen’s Show. Thousands of people learned about falconry including the new wild-take policy – so much for flying under the radar! In May, the OHC, along with NAFA and other Canadian falconry clubs put together a booth and display at the National Fish and Wildlife Conservation Congress in Ottawa. For four days we presented falconry to a national audience of wildlife managers and had opportunities to meet with officials from several provinces and the Canadian Wildlife Service to discuss a variety of falconry issues. We met both current and former Ministers and presented them with a token of our appreciation. With all this press and high-level attention, falconry sudden has a very elevated profile. This is a good thing as it means falconry is becoming “main stream”. It also means that we have to step up and make sure we build on the momentum. One example of this was partnering with the MNR to develop a random draw allocation system for the permits, developing the software and then executing the draw. Another example is the first apprenticeship workshop held in August for 35 prospective falconers. As a Club, we have worked hard for many years on many levels. We have established excellent working relationships across the board and built a positive reputation for falconry. So many members have contributed over the years that I could not begin to thank all of you here, except to say that your efforts have made the OHC the most effective falconry organization in the country. I am sure the wild take means something different to each one of you. I would like to leave you with my perspective on why it is so important by including an excerpt from the thank you letters I wrote to the MNR staff that helped make this dream a reality: “Working together we have preserved something ancient and unique, and allowed an extraordinary bond with wildlife to persist in a modern world that is increasing losing touch with nature. Furthermore, this achievement … defies the notion that we must be separate from nature in order to value or protect it. That is public service in the best sense of the word.” Enjoy your hawking season, and for those lucky ones who got permits, good luck trapping!

Agility is also requisite, that he may be able to attend his hawks in their flight and serve them with game, while they are hanging over his head in the air in keen expectation of it. As they will often outfly his outmost speed, his voice should be full, clear and loud, in order to be heard at a distance and to bring them back to the destined scene of diversion. They demand great regularity in their food and exercises, and he may be seldon tempted to neglect it, he must be methodical and temperate in his way of living. His love of the sport must be very intense, to animate him to undergo, undaunted, the numberless inconveniences of attendence, weather and soil, wherewith it is generally accompanied. This will make it his main pleasure to be always with his hawks, training them to obedience, correcting their faults and consulting their health and beauty. To do these things effectually, he must understand their temper and constitution and ought to possess much patience and mildness in the application of his knowledge. Hawks under the management of a man thus qualified, will be always in good order for flying, exhibit the greatest boldness and address in chasing their prey, give the highest pleasure to the beholders of their motions and do just honor to the skill and attention of their keeper. - James Campbell in A Treatise of Modern Falconry 1773. 2012 The Imprint EDITOR’S NOTES Yukio Yamada The Imprint is going “green.” We are building the under-utilized OHC website. This is very exciting as the OHC member will be connected like never before. New possibilities include; a members-only section that is password-protected, a news section, a bulletin board, relevant links, new product reviews, video and pics of great slips. In time, it will be possible to download the Field Meet’s Keynote speaker’s presentation. These are just some of the features of this digital portal. The OHC website team is being developed. Louise Engel, Gary Selinger and Martin Gelynse are active and they will be joined by Liz Dubas and Tom Goldsmith. Liz is one of few falconers with the where-with-all to bring her camera into the field. Tom is a great illustrator and writer. He has provided much artwork for The Imprint including this issue and is also the hunting dog columnist for Ontario OUT OF DOORS magazine. Talk to any of the people mentioned if you have anything to “bring to the table” for the website. The Imprint has been published for several years and it has met its objectives - to raise the club’s profile and to provide a communication tool for members. Yah, there were some typos (spelling errers) and not everyone agreed with everything in the magazine. But it is said, “if its in-print its history.” Welcome to the digital age of instant communications. As for the mag’s first objective - The OHC has a very high profile with falconers second to none. Finally, I thank all the contributers to this magazine and the tireless efforts of those who are dedicated to improving the club and Ontario falconry. OHC members are quick to assist other members and are very generous as can been seen by the quality and quantity of donations to the Field Meet’s raffle. I also thank the advertisers to the magazine for their support and product donations to the Field Meets. The OHC cordially invite the advertisers to our Field Meets to see Ontario birds in action. We will offer online banner ads and we will contact you about this. You maybe able to have print ads as the OHC is considering publishing an annual or special one-off issue. The Imprint could not have been published without the support of Rob McCallum and Delphax (www.delphax.com). This falconry-friendly company printed the inside pages at no charge. It has been my privilege and honour to serve as your editor and I look forward to getting in the field with you. Good hunting. 6 The Imprint 2012 Ontariohawkingclub.org Marshall Telemetry ad Ontariohawkingclub.org 2012 The Imprint REVIEW OHC president Martin Geleynse was acknowledged for his tireless work handling the club’s affairs and enhancing the sport of falconry in Ontario.

I am so honoured to be here.” he said. In his easy-goin-way, Brewer talked about Red-tails and entertaining marriage tips. “The Red-tail is the workhorse of American falconry” he said. He believes that falconers have yet to realize the potential in Red-tails. He said that there is no such thing as Red-tail bad behaviour. The bird just does it. The bird’s surroundings and thus various stimuli brings out different behaviour. The falconer must understand how behaviour is generated through stimulus as the bird is always communicating with the falconer. He discussed his Red-tail training techniques. He freelofts his bird and has 16 inches between the perch and window. His perches are high because the bird prefers to be looking down. Make sure that the door opens to the outside because the bird will try to fly to the top of the door when the door is being closed. 2012 Field Meet keynote speaker His weight management is give ot take a quarter ounce. The Initial Response Weight for a newly-trapped female is established by taking ten percent off her empty weight (Optimum Weight). Wait 48 hours to get the Optimum Weight if the bird has a crop or 24 hours if the bird has a casting. He flies her on a 25-foot creance (total 50 feet flying distance). The bird flies for three times. Then she flies free. He calls her immediately with a tidbit before she settles on a branch and gets her bearings. He also uses a lure and a hood. When the bird is on the lure, he moves his hand in and out and around so she gets used to his hand. Brewer said that that the falconer must be sensitive to her time frame and move in after she starts plucking. Then the bird can be traded off. He believes that the female is superior to the male because of its superior strength. “I fell in love with the red-tail, and to this day, I believe them to be the best birds in falconry” he said.

She tames quickly, is easy to handle and best of all she’s a spectacular hunter capable of astonishing agility, speed and determination. By the time she is in your hands she has already learned how to use the wind, developed her own specialized hunting style and knows how to avoid predators which is unlike an eyass. 2012 marks an exciting new era for the sport of falconry in Ontario – the wild take. This luxury has been afforded to almost every other jurisdiction in North America where our sport is regulated. As a result, falconers in these areas have been able to gain experience and learn from each other, resulting in a stronger knowledge base from years of experience on how to best successfully hunt passage birds in a particular region. It’s exciting to think what Ontario falconers may be able to achieve as they continue to discover and learn about their newly acquired wild birds. It’s a wonderful time to be a falconer in Ontario. Originally from the Ottawa area, I flew Harris’ hawks and later goshawks before moving to California four years ago. Since that time, I have been fortunate enough to surround myself with some expert Merlin falconers who have shared their decades of knowledge. I am in no means an expert on Merlins and I am learning all the time. So far, I have successfully flown one female (flying weight of 200 grams) and two jacks (flying at 150 grams). This is my attempt to share some of those experiences with you. A few days of heavy rain had left a favorite sparrow field muddy and full of standing water, perfect for snipe. As I approached a muddy shoreline a lone snipe burst from my feet and gave the characteristic “SCAAIP” call as it flew off. I thought that there had to be more than one. I un-hooded “V”, my dark passage female Merlin and she quickly mounted up above me. When she was in position, I ran in, clapping my hands, wildly thrashing and stomping about, hoping to flush up another bird from the mud. My efforts worked as I heard the beautiful alarm call of another fleeing snipe. I looked up to see my falcon folding over and powering down in a shallow stoop. She came down in tight cork-screw dive and smacked the fleeing shorebird in a Ontariohawkingclub.org puff of feathers. The Snipe however was un-phased and proceeded to fly towards the horizon with my Merlin in hot pursuit. I pulled my binoculars up and watched them fly off out of sight over a busy road and into a business area. A sense of amazement from the power and determination of the Merlin and a sense of helplessness of my current situation hit me. With the help of telemetry, I found her a short while later with a full crop and a half eaten snipe in her feet. She chased that bird more than a mile and a half. She was never going to give up until it was in her talons. At the suggestion of my experienced falconer friends I had been using a fast track approach when training Jacques (after Villeneuve the F1 driver). It’s said that you should try and get your Merlin on the wing and over wild quarry as soon as possible while they still have some wildness and are still in strong condition. If you spend too much time training the bird to the lure they will become “soft” – flying about you at a low pitch or worse, landing, waiting for the lure to be thrown. I had trapped Jacques not more then ten days before, and today was going to be his first free flight. I had done the creance training and given him bagged sparrows on a string to reinforce the make-in processes and wanted to get some wild birds under him. The idea was to allow him to take to the sky and as he circled around, flush some birds to get his attention. He would then turn to chase the quarry flushing at my feet before they dumped into the cover. As he climbed away again, I would flush more to keep him interested in staying overhead. As he turns back my way I would throw out a sparrow on a string for him to catch, positively reinforcing my purpose in the field as his helper. The session was going to be short and sweet. The field I selected was perfect – lots of birds and high cover for them to escape into. I had a young lady alongside who I was eager to impress. Jacques had been fairly predictable to date so I was not too concerned about looking foolish. I removed the jesses from his anklets and walked ahead confidently. I paused and slipped the hood from his head. He looked around nervously, continued on page 14 2012 The Imprint 13 Rob Conohan with his light-guage feathered shotgun. This jack flies at 150 grams.

He stared far off into the distance not interested in the countless sparrows flicking about at our feet. With a quick rouse and a mute he was off, pumping hard for the horizon. I thought “ugh oh...looks like he’s heading for the pacific...this isn’t good.” But I didn’t dare say it. His flight was direct and filled with purpose. Did he see something he wanted to chase? Remaining calm and pretending like this was part of the plan, I watched him as he shrunk into a smaller dot into the sky. I pulled out his beloved lure and started swinging it to get his attention. He was still climbing, up and away. Then at about two hundred feet up and too far out to tell what exactly was happening, the dot that was my Merlin dodged to the left and then to the right, then started sailing back to the earth. “I think he just caught something!” my friend yelled out. “I think your right!” I excitedly replied. He had blasted off the fist with the intent of catching a bird cruising by far up in the sky. Jacques at least had the courtesy to fly back in our direction before diving into one of the many rows of the immense, covered raspberry fields which bordered this hunting area. With the help of my telemetry, I was able to locate him. He was plucking his prey. However, the failing winter light and covered rows made it difficult to spot him. I slowly crawled up on my belly with a freshly opened sparrow in my hand. I would inch forward when he took a bite and stop when he stopped, ready to offer a tid-bit and pick him up. Then when I was inches from securing his prey, he bolted into the darkness of the raspberry rows. “s@&t!!!” my friend tried to help locate him for a bit but had a prior engagement so had to leave. This was going from bad to worse. Dejected, muddy and grumpy I finally gave up well after dark. All was fine the next day as he was located the next morning and retrieved easily. As for the girl, lets just leave that one alone. Jacques turned into a steady partner and strong flying game hawk. He was released back into the wild after a successful season. It is important to note that although some Merlins can be difficult to pick up when they are with prey and will have a tendency to carry. With patience and conditioning most tame down nicely and let you pick them up with no problems. continued on page 16 Ontariohawkingclub.org By Eric Edwards Beach Trapping When it comes to trapping merlins on the beach the Dhogazza reigns supreme. I carry a variety of net sizes with me when I head out trapping but I typically use a pair of three foot by six foot nets arranged in a shallow “V”, with the point of the “V” aiming north (or the direction the merlins are coming from). Some situations may call for different configurations like a three-sided “backstop” but the “V” rarely fails me and makes the nets harder to see. Each corner of the net is cable-tied to a small steel ring, these rings then slide onto half-inch galvanized conduit poles. The top rings have two-inch long pieces of monofilament tied to them. I attach a wooden clothespin to the top of each pole to act as the trigger mechanism. The clothespin holds the piece of monofilament, holding the net up. When the bird hits the net the monofilament pulls free from the pins and the rings slide to the ground collapsing the net on the merlin. The lure bird pole is placed in the corner of the “V” and the lure bird is given just enough line to reach the ground. Next, I have a pole, straight back, twenty feet from the first pole, with an eyebolt at the top. I run my lure line from the lure bird, through this eyebolt and back to the blind. This allows me to position my bait bird exactly in the center of the nets and it’s not necessary for my blind to be directly behind the nets. The English sparrow is the best bait bird and I use a lure pigeon on a separate pole about ten feet from the nets. The pole for your lure pigeon should be at least 10ft high so you can get the pigeon high into the air. The pigeon is used to lure in birds from a distance, once the bird is close enough to see the sparrow drop the pigeon and bring the merlin in to the sparrow. It’s important for the pigeon to be out of sight when it’s dropped, either into tall grass if available or you can even provide a bucket for it to hide in or dig a hole for the pigeon to hide in. Otherwise the merlin may keep coming at the pigeon and never see the sparrow. The background is the most important element for success. It’s very important to make sure you have a dark background. Stand about five feet away from your nets, on the side the merlin will be coming from, and get down on your hands and knees so you can see what the merlin will see. If you see sky behind the nets they are too visible. You need a dark background to make the nets disappear. If you don’t have such a natural background available there are a few props you can take with you. I have several small arti- Ontariohawkingclub.org ficial Christmas trees I carry with me and I have found the best and easiest solution is camouflaged cloth stretched between two poles Hunting Lets get one thing straight, although merlins and kestrels appear similar in size, as predators they could not be more different. A good friend of mine and experienced Merlin falconer provided me with the perfect analogy, “Mother Nature took both birds, put a VW engine in the kestrel and a Porsche engine in the Merlin”. Any thoughts of hunting a Merlin in the way you hunt a kestrel should be abandoned if you want to see the true potential of this bird. Merlins are extremely determined, persistent and have the ability to show tremendous speed in a stoop as well as level flight. Here in Southern California, Jacks are quite popular. When provided with the correct opportunities they give wonderfully sporting flights at sparrow sized birds from a pitch. They have also been known to take larger prey (I had a Jack take a snipe which flushed as I was running in to flush a sparrow), but these quarries are best left for the female. I suspect that she would be the better choice for falconers in Ontario due the difficulty in finding smaller quarry during the winter months. Although typically less co-operative in providing a classic waiting-on flight, she has the potential to catch anything from sparrows to starlings, doves and pigeons. I can’t wait to see what Ontario falconers achieve with these birds in the coming years. Eric Edwards is a well known Merlin Falconer from Florida. 2012 The Imprint 15 to be feed as such. No Gold medals were ever won on a diet of fast food and soft drinks . PASSAGE MERLIN continued from page 14 Preparation for the Bird More than any other falconry bird I have flown, the Merlin requires specialized equipment and planning prior to acquisition. Perch: A small 4” diameter indoor block perch, works great. Hood: Obtain a selection of good fitting hoods. Robert Helsom (www.helsomhoods. com) is a dedicated merlin falconer and makes high quality, light and well fitting hoods. A bulky heavy hood will most likely result in a grumpy, hard to hood falcon. Anklets: Use the smallest grommets available. Shoelace grommets work great and the setters are available and most crafts/fabric stores. Tip: Cut small pieces of plactic bandaid and wrap it around the tarsus under the anklet. This will prevent scale damage and reduces the chances of him biting his toes and damaging himself. Jesses: Try to use short and narrow jesses. Bulky equipment around their legs will make them uncomfortable and could also lead to them biting and damaging their toes. Food:This is probably one the most involved aspects of flying a Merlin. You need to trap or shoot your own food for your merlin. House sparrows and starlings are readily available. Elevator or funnel sparrow traps work great and an accurate scoped pellet gun loaded with NONLEAD shot helps fill the freezer when the traps are less productive. A diet of Quail is not enough to sustain a Merlin to the point where you will see her full potential. These falcons need to be feed a diet of small birds like they do in the wild. These birds are little athletes and need Trapping Merlins do not breed in California and only occur here during the winter months. They typically show up towards the end of October and a large number stay until March, feeding on the migratory songbirds which also winter in southern California. As a result, Merlins can be fairly easy to find here. All that is involved is driving into an area with a high density of small birds and looking for these diminutive falcon sitting atop a dead tree in the early morning. Merlins can be differentiated from kestrels at a distance by their shorter tail and broader shoulders. They resemble a stocky football player while a kestrel will appear more like a q-tip and be bobbing its tail. Once a bird is spotted the Dho-gazza (which is already set up on a free standing base for quick deployment) and bait sparrows are placed in-front of the bird. In general the falcon is coming at the first flap of the bait sparrow and the falconer does not even have time to get to the car. Hooded, Socked and taped. Ready for tranport There is probably a small window of opportunity to trap a passage Merlin in Ontario which makes driving around randomly, staring at tree tops probably not the best use of your valuable time. As a result, your best bet might be to set up a more permanent trapping station along a known migration corridor such as somewhere on the north shore of Lake Erie and Lake Ontario.

Her question was “what is it?” Dubas’s mystery bird has been identified as a Red-tailed Hawk Buteo jamaicensis. Red-tails can be difficult to ID because of they have extremely variable plumage and some of this variation is regional. Most Ontario Red-tailed Hawks are rich brown above and pale below, with a streaked belly and, on the wing underside, a dark bar between shoulder and wrist. The tail is usually pale below and cinnamon-red above, though in young birds it’s brown and banded. “Dark-phase” birds are all chocolate-brown with a warm red tail. “Rufous-phase” birds are reddish-brown on the chest. A Great Plains race called “Krider’s” hawk is pale, with a whitish head and washed-out pink in the tail. Light-phase western birds tend to be more streaky on the underparts than eastern Red-tails; south Texas forms are darker above, without the dark belly band most other Red-tails have. Dark-phase birds Ontariohawkingclub.org can occur anywhere but are more common in western North America - particularly in Alaska and northwest Canada, where the all-dark “Harlan’s” race is common. The “Harlan’s Hawk” breeds in Alaska and northwestern Canada, and winters on the southern Great Plains. This very dark form of the Red-tailed Hawk has a marbled white, brown, and gray tail instead of a red one. It’s so distinctive that it was once considered a separate species, until ornithologists discovered many individuals that were intermediate between Harlan’s and more typical Red-tailed Hawks. Jerry Liguori reports in Birding March 2010, in the U.S. and Canada, there are as many as eight recognized subspecies each with its own degree of plumage variation. There is also overlap among the subspecies. continued on page 18 2012 The Imprint 17 RED-TAILED HAWK continued from page 17 Reprint from Comparison of Harlan’s with Western & Eastern Red-tailed Hawks By Jerry Liguori and Brian Sullivan in Birding March 2010 markwilliamsphotographer.com Liguori writes; Much is yet to be learned about plumage variation and overlap in Red-tailed Hawk subspecies. As more birds are studied and photographed, the issue should become better clarified. However, since Red-tailed Hawks seen during migration and/or winter are difficult to classify to subspecies with certainty, good photographs of breeding birds are critical for making assumptions about the geographic variation within the species. A concerted effort to better understand the breeding biology of Red-tailed Hawks in Alaska and western Canada is needed. We encourage birders to contribute to an online gallery <http://tiny.cc/h2c4C> of photos of breeding Red-tailed Hawks. In Ontario, we do not have to concern ourselves with the Harlan’s or Krider’s Red-tails but the variations make for good reading. Listed is the literature cited in Liguori’s article which is a good starting point for those falconers seeking more Red-tail info. Fig. 6a.

Perhaps this is obvious to others, but it was the first time I noticed that a baby Harris’ Hawk, even at a couple of days of age, will always be more interested in reaching for a piece of deep red meat rather than a piece of pale red meat. I realized that these birds hatch with the innate ability to distinguish between the colours of the prey offered, and they will always select the darker meat i.e: preferring the deep red organ meat (heart, liver) instead of the paler muscle meat. When you think about it, the organ meat is full of blood and nutrients, is softer, and is easily digestible. It is tricky to know whether this ability to distinguish colour is based on an inherent knowledge or an instinct, but there is no doubt that the Harris’ chick is equipped with this ability at the time of hatching. They are able to see very well with those tiny beady black eyes. It suggests that it has the natural programming to choose deep red. Ophthalmologists have researched the raptor’s eye and vision and it is known that they see in colour. As the young hawks matured week by week, I carried this observation into my training by offering deep red meat to entice the birds to fly toward me or toward a target for food reward. Combined with variable reward, that is, varying the amount of food and type of food given, thereby peaking the bird’s curiosity and natural drive to be keen to chase. Variable reward also helps the bird gain confidence as it repeatedly flies to a target and is always rewarded. Harris’ Hawks are so agreeable and quick to learn that they soon come to the target as much out of curiosity as for the food reward. I found that the technique of being able to offer deep red meat as an extra incentive to come to the glove was really helpful. We take so many things for granted when working with Harris’ Hawks. Their very nature makes it easy to train them because they are so responsive. It is no mistake that Harris’ Hawks are by far the bird continued on page 20 Ontariohawkingclub.org 2012 The Imprint 19 Yukio Yamada photo It has long been surmised that parent birds emit nutrients through their saliva as they give mouth to mouth feedings to their babies. HH OBSERVATIONS continued from page 19 of choice used by beginner falconers and bird show handlers around the world. In the nest while being parent reared, Harris’ learn to behave with a nest etiquette, waiting for the prey bits to be served to them. When you watch parent birds feeding their young, it is amazing to notice how small the pieces tend to be that they offer. And as their offspring matures, they automatically react by giving somewhat larger pieces and maintaining order in the nest. It has long been surmised that parent birds emit nutrients through their saliva as they give mouth to mouth feedings to their babies. Vulture chicks hatched in captivity are often given enzyme supplements or are given food already partially digested from within a vulture’s crop. I would guess that this is the case with many raptor species, and probably the Harris’ Hawk is no exception. Again because of their very gregarious nature, it is common to see Harris’ fly in a cast, often with falconers flying their birds together when the birds haven’t ever been carefully introduced. In conclusion, at hatching the Harris’ Hawk has some natural programming built into its hard drive that we can learn to use to our advantage as we develop a co-hunting regime or a working relationship with them. Mourning Doves on Menu? Notes from Mourning Dove population dynamics and societal assessment towards a proposed hunting season in Ontario. Long Point Waterfowl Technical Report No 2007-1 Mourning doves (Zenaida macroura)) are one of the most abundant birds in North America, and it is suspected that their populations are increasing in Ontario. Due to the abundance of this species, and the economic importance of its harvest in the U.S., the Canadian Wildlife Service, Ontario Federation of Anglers and Hunters and Ontario Waterfowl Advisory Committee have discussed the possibility of opening a season to harvest doves in Ontario. Based on Christmas Bird Count data, dove populations showed rapid increases in all jurisdictions studied; Ontario’s winter dove population increased by nearly 13% per year between 1977 and 2001. No detectable difference in indices of winter population abundances for all survey years examined. Also noted are similar annual fluctuations 20 The Imprint 2012 in winter indices of dove abundance between all hunting and nonhunting jurisdictions. This suggests that changes in winter populations within the hunted and non-hunted jurisdictions were driven primarily by intrinsic and/or extrinsic factors exclusive of hunting. Northern jurisdictions had the fastest rates of annual increase in wintering populations (Ohio’s wintering population was seasonally stable after initiation of a dove season), possibly due to northern range expansions. With comparable abundances to the hunted and non-hunting jurisdictions in the U.S. and no evidence suggesting that hunting negatively impacts wintering populations; it is likely that an Ontario dove harvest would be biologically sustainable. Ontariohawkingclub.org The Ice Can Still Be Broken! By Ulrich Watermann T urkey Point Ontario 2010. The phone call came on a Wednesday morning. “Guten Morgen mein deutschen Freund, wie geht es?” The raspy voice revealed Hal Webster, who was calling from Bob Woodroffe’s residence near Moose Jaw Saskatchewan. I answered in German, “Sehr gut Herr Oberst. Leutnant!” The conversation then fell into English. “We are taking two ducks daily with Oscar and Coconut. It is going great and the weather is fantastic. When are you coming?” “As soon as possible, I just have to arrange a few things and I will be on my way.” He answered,” Get your butt in gear and come over here as long as the weather is good. Bye!” I called Penny Lalonde from the Saskatchewan Game Department and informed her of my intent to visit, faxed the required band numbers of my birds and had the necessary permit back in about an hour. I thought that if all the civil servants in Canada were as friendly and efficient as Penny Lalonde, this country would be a lot more fun to live in. I headed west two days later with two Saker-Gyr hybrids, a male and a female, both flown to the kite but totally unproven on game. I arrived Sunday noon. After the usual greeting ceremony which included a “wee dram” of single malt, the birds were perched in the rolling hills north of Moose Jaw and each given a crop of fresh gadwall caught by Oscar the seven-year old jerkin that very morning. Coconut, Hal Webster’s black first-year male Gyr-Peregrine, was flown later that evening, showing amazing ability in taking a Gadwall hen from a height of 600 to 700 feet. Oscar, Bob’s jerkin, in his seventh season, was flown the next morning near a slough that held numerous ducks of several species. Bob’s technique to have a good hunting flight is to drive up to two kilometers away from the pond or slough, put the bird on the roof rack and drive towards the ducks. The falcon will then leave the vehicle at his leisure and climb, following the truck to a height of about 1000 feet, arriving at the water. Bob then jumps out to flush the ducks. Oscar goes into one of his spectacular stoops to single out a duck and with 95% accuracy makes a kill. This flight was successful as well and a Widgeon was taken for the larder. Ontariohawkingclub.org At around noon my birds were both flown to a baggie each which they took with ease. When I came back to Bob’s place, three more falconers had joined us: Dave Doughty with his adult female peregrine, Pasquale Hines and Matthias Hoelscher who was visiting from Germany. Coconut was flown in the evening with everyone enjoying the successful flight. The hen Gadwall kill was celebrated in the field with a round of “Buds” and then later on at a social at Bob’s place with a hearty meal including some refreshments. Oscar the jerkin showed his skill the next morning by taking another duck in classic style. Dave Doughty’s peregrine was also flown and took a gadwall in spite of being interfered with by a wild adult Peregrine female. I tried my birds at wild ducks that afternoon but both birds were harassed by wild falcons – a peregrine and a prairie. My male’s right foot swelled up from a previous injury. This problem in spite of being treated rendered him unflyable for the rest of his stay in Saskatchewan. Oscar and Coconut were flown the next day. Oscar had success while Coconut made a spectacular flight but came up empty handed. He did not seem to be serious since Bob was still experimenting with his ideal weight. I flew the female again only to be interfered with by another Prairie Falcon. The next day, after Oscar and Coconut had flown, I tried my female falcon again, and sure enough, she was hassled again by a female Prairie. I stated to Bob “I know my bird has potential in spite of only 37 ounces flying weight. I would like to try her at Snow Geese.” “Well”, Bob answered. “Let’s get a good slip for her.” It did not take long for us to spot a dark cloud of mingling Snow Geese in the distance. We rushed toward it. A waterlogged slough revealed tens of thousands of geese with just as many mingling about in the air. We drove back out of sight of the geese and I put the hooded falcon on my fist. This was the first time she was flown off the fist out of a moving vehicle. We passed the slough and saw thousands or more geese over drier ground a mile ahead. The geese were on the left side of the truck some 200 meters into the fields. continued on page 22 2012 The Imprint 21 WATERMANN continued from page 21 I unhooded the falcon, she tensed up immediately, bobbed her head and off she went underflying the flock of geese. Once she reached the other side of the flock, she stooped up and zoomed with rapid wingbeats into the flock of spooked geese. She singled out three birds and closed in on them. Bob and I followed on the grid road as fast as we could. We started to get excited. The falcon, still chasing the three geese, suddenly stooped downward and we lost sight of her because a small hill on our left blocked the view. Coming from behind the hill, we spotted the falcon rolling on the prairie grass with a white goose. “She got one!” we both shouted. I almost collided with another truck while stopping perpendicular on the country road. “Look after the truck!” I yelled to Bob and then probably broke a speed record for a guy my age running through the prairie to help my bird. The goose, a large adult gander, tried to beat the falcon off, however I grabbed him by one wing and let the falcon nick him off. Bob came to the scene and congratulated me and I thanked him for helping me find the slip. The falcon was allowed half a crop from the head and neck of the gander. I then hooded her and put her in the box for our journey home. Taking a little detour, we stopped at the local liquor store to buy a bottle of single malt and a bottle of “Mumms” for “Nairy”, the lady of the house who would have to endure us reminiscing about the successful flight. 22 The Imprint 2012 Good old Hal Webster’s eyes popped when we entered the house to weigh the gander. The gander came in at just under 6 pounds with about 2 ounces missing from neck and head. Hal, who was a bit under the weather, stated that he under no circumstances would miss the next chance to see my falcon take a goose. Bob flew his two male falcons the next morning, supplying fresh meat for the larder. My falcon was somewhat too heavy to be flown so we tried her in the late afternoon. We located a large flock of geese and I flew my bird off the fist. The bird flew listless and ignored the geese. When we arrived home, I let the falcon gorge on the goose carcass to re-confirm her. This was a mistake since the bird simply did not turn the crop over and only reached flying weight again after three and a half days. Bob had an interesting flight the next morning with Oscar. Oscar took off from the vehicle as usual towards a slough, gained good height but then showed no interest in the ducks below him. We drove along the slough when suddenly an immature Bald Eagle took to the air. Oscar went immediately into an angular stoop and smacked the large predator so hard that a plume of feathers seemed to explode off the rump of the eagle. Oscar had done his job and let the eagle get on his way. Father John, an avid outdoorsman, had joined us for another try at the large quarry. Bob worked his birds first. Oscar Ontariohawkingclub.org Opposite page: Clouds of Snow Geese. Below: Watermann. No further words needed. singled out a hen Mallard from a large group of ducks and thumped her into the ground. Coconut, a little too heavy, just toyed with the ducks and was called back to the lure. We kept driving through the rolling prairie scape entering a valley with the opposite side white with geese. I motioned Bob to stop his truck. We drove out of sight, I put the falcon on my fist and entered the valley again. Coming within range of the geese, I unhooded the falcon, who headed straight for the geese which started to fly by the sight of the attacking raptor. The falcon headed straight for the closest one, knocked it down, to follow it up by grabbing it on the ground. When I arrived the goose was dying. Her left wing was broken and her neck was ripped wide open. Father John congratulated me and Hal Webster and Bob Woodroffe were delighted to have witnessed the “knock-down” from their truck. The next day saw us concentrating to find a good slip for Pasquale’s Gyr female “Angel”. A long slough– on one end waterlogged, offered the opportunity. Tens of thousands of geese were on the ground and in the water with large groups still coming in to land. Pasquale put the unhooded falcon on the truck. The large falcon seemed to ignore the numerous quarry but took flight anyways with slow wing beats. She gained a height of about 800 feet and drifted away circling down the slough. Eventually she circled back slowly all the while pretending to have no interest whatsoever in the geese below her. Suddenly her silhouette became sleek, with rapid Ontariohawkingclub.org wing beats she dove at an angle into the flock where I lost sight of her. A moment later, she stooped upwards out of the flock with a speed only a gyrfalcon could achieve and with a rolling stoop, knocked a young goose straight out of the air. Pasquale ran to aid his falcon on the ground but not much help was needed. Angel was the master of the situation. I consider Angel’s flight the all over best performance by a gyrfalcon flying at large game that I have ever seen. This sentiment was shared by Hal Webster. Now it was my bird’s turn. We located another flock of geese mingling about and feeding on a harvested pea field. The falcon showed no interest and drifted out of sight. I used the receiver and got a signal from far away. Following the grid roads, we zeroed in on a farm with a large shelterbelt. I swung the lure but no response. The signal came in at times quite strong then disappeared. By surrounding the farm we made sure that it was the source of the signal. Pasquale and I approached the farm on foot. I ran from one side and Pasquale from the other. Over and over again, a strong signal was followed by a weak one. “What was going on?” I asked myself. The signal got stronger only to disappear yet again. I zigzagged through the shelterbelt taking readings. There it was again in the high grass right in front of me. I rushed in and found my bird duking it out with a horned owl with another horned owl just two meters away in a tree ready to join in on continued on page 24 2012 The Imprint 23 WATERMANN continued from page 23 the melee. I yelled running towards the blob of feathers. The birds finally took note of me and they took off in opposite directions. I cleared the bush, swung the lure and secured my seemingly uninjured bird. “No reward for you!” I exclaimed to the bird. Bob and I discussed the naming of my falcon and we came up with the name “Boudecia” after the English warrior queen. After Oscar and Coconut both had taken ducks the next morning, Pasquale tried Angel again however the bird was a bit too heavy and ignored the geese. Boudecia was flown next. She hit a goose but failed to bring it down. She was frustrated and landed on a hydro pole. I called her down. In the late afternoon we discovered another goose-filled slough. Bob stopped his vehicle with Hal on the passenger seat. “Do you want to fly this?” he asked me. I replied, “Of course! Get yourself a front row seat!” Bob parked his truck in a good viewing location and me with Pasquale on board, drove out of sight. I put Boudecia on the fist and we raced towards the geese first on the road and then over the fields. The geese started to fly up as we approached. I unhooded the falcon who wasted no time to attack. She at first, flew into the mingling mass of geese, then over climbed them, went into a shallow stoop and bound to an adult goose close to the ground. Several other geese tried to help out to get the falcon separated from their mate. But Pasquale and I arrived and helped the falcon to secure her quarry. Hal and Bob watched 24 The Imprint 2012 the kill take place right in front of their noses. They congratulated us and Hal stated, “Well, you Ontario boys have broken the ice wide open and turned over a new page for modern falconry!” We were proud of that comment. Geese have been taken by falcons before, mainly as an unintended target or as professional setups at airports. We all celebrated the last two weeks achievement that very night for the last time since it was my last day of our trip. I packed up in the morning and headed east dreaming of more “icebreaking” either by flying Golden Eagles at Coyotes or flying female Gyrfalcons at Sandhill Cranes. Both are inviting possibilities in the wide open spaces of the Canadian prairie.

I have since used this system for a couple of seasons and recently spent a few days in the Utah salt flats doing some long range field tests and comparisons with other manufacturers transmitters. Here are some of my findings. Photos by: markwilliamsphotographer.com The 433 mhz frequency is not new to falconry and I was aware of it being widely adopted in Europe for over 20 years. In recent years, it has really caught on in the UK and the Gulf. One of the obvious attractions is the fact is uses much smaller antennas on both the receiver and more importantly the transmitters. This is a huge benefit when tracking an errant bird while using it inside the small confines of your vehicle. The transmitter antenna is a mere 7 inches which is ideal for any mounting method and reduces chances of electrocution if it must be worn on the leg, (something I hate doing myself). Although admittedly I am biased, the use of a leg mount is the least effective position for signal transmission. The antenna is often laying flat on the ground and if the ground is wet in particular, it dissipates the signal transmission. The use of a backpack, tail mount or even neck mount produces superior signal transmission and positions the transmitter antenna in a vertical position compared to horizontal of the leg mount version. If you ever do a signal test comparison, lay one transmitter on the ground and one hanging vertical from a wire and you’ll see what I mean. As you walk around the signal of the one laying flat will vary, particularly when you are facing the end of the antenna facing directly at you. Depending upon how continued on page 26 Ontariohawkingclub.org 2012 The Imprint 25 433 vs 216 transmitter length PRODUCT REVIEW continued from page 25 the bird is positioned on the ground with a leg mount as you walk around it, the signal may appear weak. Imagine this in a none controlled situation and you could miss the signal in your search if you are at a distance or are in a moving vehicle and passing by at this angle while tracking. However I have since learned the real virtues of the higher frequency system is it’s performance characteristics in areas of high “noise”, i.e. cities and urban areas. To clarify, much of the limitations of signal transmission / reception is caused by “noise”. By this I mean atmospheric noise like TV and radio signals bouncing around the atmosphere and in particularly within highly populated urban areas. For some falconers, these areas are the very arena of their hawking grounds. The much higher frequencies like 433mhz seem to cut through the outside noise interference, which makes for much clearer, less statically sounding signal reception. Furthermore speaking to Marshall Radio’s Chief Science Officer Dave Marshall, he too extols the virtues of the 433 frequency from a physic’s / design perspective. Without getting too technical, he tells me that the properties of the UHF 433 mhz band will always radiate more effectively in a falcon transmitter and hence with same power in, will radiate more power out. Furthermore, in any transmitter the antenna system is comprised of TWO parts, the active or fed element (main antenna) and the “counterpoise”. The active element or antenna, needs a ground plane to push the signal off when broadcasting, much like the omni antenna does when using the metal roof of the vehicle. In a falcon transmitter, the counterpoise is basically everything conductive on the opposite end of the base of the antenna. This can be the circuitry inside the transmitter, the battery and even the tail or backpack spring if so equipped. There is even some coupling to the semi-conductive mass of the falcon itself (backpack, neck and tail mounts that is). Hard to imagine your falcon is part of the antenna but it is. As mentioned, I was recently invited down to their Salt Lake City, Utah head office to do some field testing, along with North American Distributors, Dave Frank, Brad Woods and Mike Syring along with Marshall’s Managing Director for Europe, Stephen Lea who come over from the UK specifically for this. What we witnessed really impressed us all. 26 The Imprint 2012 We had three other manufacturers transmitters to compare alongside with Marshall’s RT, RT plus, Micro and Turbo transmitters all in 216mhz. In addition to these we had a Marshall 433mhz receiver with the Micro, Scout and Turbo transmitter. We placed them all on a string hung between two wooden posts and at equal distances apart about 4ft high. The location was up high on the side of a mountain escarpment overlooking the east side of Salt Lake City. We then drove west outside of Salt Lake and taking readings all the way. The competitors version of the Micro lasted about 500 yards ! We continued through the city past a radio/TV station and still got a signal with every transmitter but it clearly illustrated the improved signal reception of the 433mhz receiver compared to readings of the 216mz that buzzed with outside interference. We continued west and then deliberately turned south and along the base of a high mountain where we lost the signal of both 216 and 433 mhz within 20 yards of each other. The purpose was to evaluate the signal propagation from behind high terrain. We then carried on west and to cut a long story short, we lost the 433mhz Micro at 52 miles and eventually when we reached the Nevada border 110 miles from the transmitters and were able to scale 50ft up a hillside and get signals from 216mhz Turbo transmitter and when we climbed 50feet higher also with the 433 mhz Turbo. I have never been able to hear a signal from 110 miles before and it was quite a feat of transmitter performance. Imagine going up in an airplane and being able to pick up a signal for a considerably further distance and not competing with the curvature of the earth that begins after a mere 4 or 5 miles. The bad news is that the Turbo is not currently available in either North American or European markets. However, to get a signal with a 433 mhz Micro transmitter at 52 miles is pretty amazing and much further if using a RT transmitter. We have all heard that 433 MHz (UHF) does not propagate as well over real terrain as does lower frequencies like 216 or even 151 MHz, but our field tests showed that the wizards at Marshall Radio have found a way to engineer around this and now produce UHF equipment that in most cases, outperforms all current 216 systems on the market. With this closing of the gap, there is a greater incentive to switch to a smaller unit that uses a much small antenna transmitter and has much greater resistance to noise interference. This being said, adopters of the 433 system will definitely find a difference and period of adjustment when tracking (if comparing to the 216mhz), Ontariohawkingclub.org Ontariohawkingclub.org Wearing two transmitters. Gyrkin wearing tail and backpack transmitters. Photos by; markwilliamsphotographer.com as the directionality of the higher frequency is more acute. Personally I am seeing more positive reasons to switch to the 433 system. One of the other factors that might come into play when considering switching to a 433 mhz system, is the fact falconers may ask themselves “what if I lost my bird and no one else has 433mhz” ? I thought about this myself, but like many I have since asked, I cannot think of a time that I lost my bird and had to call in someone else to help. It happens I know, I helped someone a couple of years ago with their 216 unit, but it is indeed rare. I am sure the same concerns faced those original telemetry users who used original 151 mhz frequency with 18” long transmitter antennas and then switched to 216mhz with 13” long antennas. My thoughts are that as more people switch to 433mhz this will dissipate in time as it did before. For those of us hanging out for GPS, all I can say is that from the information I have gathered, that it is realistically at least 3 years away and the French company who tried to launch it last year, found it failed and are now faced with law suites from it’s early adopters who outlaid a great deal of money for something that was not really ready for release. Furthermore when we do get GPS, I don’t think it will be quite as some might think. My expectation was that it would be like a domestic version of the very expensive wildlife research satellite transmitters that are used to track bird migrations and that sends a periodic signal (often once a day to prolong battery life), to a satellite which relays that information to a computer to tell it where it is. The other is the much shorter range of the Garmin dog collars that use a much larger transmitter than a bird could carry but transmits over a very short, perhaps 1 mile range. From what I understand that is not how it will look like for our application. While the falcon knows where it is, the challenge will be getting the information to the falconer in “real time”, not a day or so later. The way it is likely going to be applied and used into the market, is that a long range RF signal will tell you where the bird is within say 50-100 miles and then the GPS signal (which requires a very strong signal transmission from the transmitter built within the extended signal pulse), will send the signal to the falconer who will know exactly where …and how far ..or how high and at what speed his bird is flying. It will also be significantly more expensive than the telemetry units we use today. However we won’t know the facts for sure for a few years yet, so don’t hold your breath. In the meantime, I foresee greater advances with traditional RF signal units with even greater range than with what I have seen with the Turbo transmitters. I predict a transmitter with under a 4” antenna, yet with long-range performance similar to the RT plus transmitters, particularly from the 433mhz system that already only requires a 7“ full size antenna as a standard optimal performance. At this point I anticipate many more people in North America will follow the European and Gulf market falconers in recognizing the overall advantages of the 433mhz system compared to 216mhz and will switch over.

This Congress provided a unique opportunity for the local, state, provincial and federal levels of government, NGOs, First Nations, Inuit, academia, scientists, fish and wildlife biologists, media and the general public to come together and discuss the challenges facing the fish and wildlife populations in both Canada and the United States, and to develop recommendations for future action. Although much of the focus was on Canadian issues, the Congress was both sponsored and attended by a significant number of key American conservation partners and delegates, who participated in deliberations within a continental framework. The conference was attended by Martin Geleynse, Paddy Thompson from Saskatchewan, Carl Millier from Quebec, and Maya Basdeo, from Ontario/Saskatchewan. Almost 500 people attended from every province and territory and 20 US states. These people were some of the most influential and highest caliber people in the conservation movement including government officials, NGOs, academics and Stephen Harper. Detailed information of the conference can be found here http://www.nfwcc.com. The booth consisted of a backdrop provided by Falcon Environmental Services with display boards showing a variety of hunting and conservation activities. Carl Millier provided a large screen TV on which showed falconry videos. Handouts included the OHC falconry brochure, a more technical handout providing details on falconry, raptor management and conservation in Canada, as well as copies of the 2012 Ontario hunting regulation summary which highlights falconry with a cover photo of Maya Basdeo with a Harris Hawk. Martin brought his intermewed peregrine Kira who sat calmly on her high perch for 4 days without bating once. She was a big hit and even let people touch her. What was accomplished 1. Clearly raised awareness and profile of falconry and moved it into the mainstream of wildlife management. 2. Meeting provincial wildlife directors and policy people. Meeting people from NGOs from across Canada and the US. 3. Discussing falconry management in NL and NB at length. 4. Cementing relationships and friendships in the broader conservation community. Many contacts made/reinforced in the OFAH, SWF, Ontario MNR, Quebec. 5. lmportant discussions with MNR on implementation of wild take. 6. Discussions with SERM on falconry policy in SK. 7. Official and unofficial meeting with key CWS decision makers on peregrine wild take in SK and US. Received a commitment from CWS a) not to oppose take in SK and b) to re-engage with US on peregrine harvest levels and allocation. 8. Provided detailed feedback on issues related to proposal to downgrade gyrfalcon to CITES Appendix 2. Established the credibility of the falconry community on this issue and ensure that we will be consulted as events and plans unfold. 9. Established Canadian Director of NAFA as the key point of contact on national falconry issues.

First Aid Tip Unpasturerized honey is an effective agent for treating wounds. It has an antibacterial and fungal agent that speeds healing. Honey does have antiseptic properties that kills bacteria which have contaminate the wound, and further promotes healing by drawing moisture in and around the wound. OHC member and vet, Scott Craig says that preliminary studies indicate that honey alters the ph of the wound. “Sugar appears to have the same properties” he said. The bandages should be changed daily to maintain the honeys healing prperties. Problems are keeping the honey and bandage on the wound. Not an easy thing because the bird will likely try to remove it. Try hooding the bird to keep it sedate. Using alcohol or hydrogen peroxide is not good as it can exacerbate the wound and cause further cell damage. 28 The Imprint 2012 Ontariohawkingclub.org Nutrition and Training In Captive Birds of Prey By Scott Craig, DVM T he best diet that any captive raptor can have is one that is based on what it would eat in the wild. Since this is rather difficult to achieve in captivity, a balanced and varied diet mirroring as “close” as possible to what that raptor would eat in the wild is the best. Not all raptors eat the same diet. Some eat a specific diet that is very limited in animals; whereas, others are more opportunistic and eat a wider range of animals. Yet each can have individual preferences as well. Nutrition is fundamental to a captive raptor’s health and a healthy raptor is a longer lived, better feathered and harder hunting bird. Although captive raptor’s breeding has made a positive impact on the reintroduction of certain endangered species, research of raptor nutrition is still widely concentrated on the study of the wild population. Much of the scientific research on avian nutrition has been made with poultry. Poultry nutritional research gives a basis for raptor nutrition; however, with the different metabolic requirements between birds species, caution must be exercised (Forbes 2000; Chitty 2008). The scope of this paper is to review the available scientific information on raptor nutrition in four specific areas. The first area is to understand some of the basics of nutrition; the second area is to understand the importance and nutritional significance of some of the more available foods; the third area is the basis of supplementation and finally some novel ways falconers are training their birds and the importance of nutrition. For your convenience, there is a table in the second part of this paper comparing the nutritional content of the different foods that are being fed to captive raptors; you may be surprised. Basic Nutrition Feeding captive raptor can be challenging. It is important to feed the right quality and quantity of food, yet at the same time keep in mind affordability. You must be aware of the bird’s basic requirements in terms of water, carbohydrates, protein and fat, as well as micronutrients such as vitamins and minerals. Raptors are whole carcass feeders and a simple provision of meat is not sufficient (Cooper 2002: Chitty 2008). The digestive tract (gut) of a raptor is a fairly simple system. Little grinding of food is necessary in the ventriculus. The large bowel and cecum do not ferment food and are relatively undeveloped. The volume of food a raptor can eat at any one time is dictated by the crop size. There are two groups of raptors; those with a crop being the diurnal birds of prey (the Falconiformes) and those without crops being nocturnal birds of prey (Strigiforme – owls). All birds of prey will produce a casting; usually within eight to sixteen hours after eating. A casting is the indigestible part of the carcass such as bones, feathers and fur. It is interesting that these castings, if broken apart, represent Ontariohawkingclub.org a novel way that the raptors eat. Falconiformes normally tear their food apart then swallow it; whereas, Strigiforme swallow their food whole. Intact skeletal structures can be recovered from the casting material of owls. Energy is the fundamental result of any diet. The essential nutrients that a bird uses to fulfill its daily requirements can be divided into fat, carbohydrates, protein and water (Forbes and Flint 2000; Chitty 2008; Cooper 2003). Carbohydrates are not as important in a raptor diet. The carbohydrates that are built up with in the raptor’s body are from the synthesis and conversion of other dietary components. Fat is the major source of gross energy. It has twice the calories (energy) than protein and carbohydrates. It is also often the driving force for the prey choice of wild carnivores. Prey selection in the wild is often chosen on the largest and often plumpest animal (Taylor 1991). Fat is an extremely efficient source of energy which is readily absorbed and can be stored in the body’s fat deposits for future energy demands. Meat high in fat is energetically more valuable than a diet which is all protein, such as rabbit (Forbes 2000). A diet deficient in fat may be exemplified as dry scaly skin or brittle feathers. The fat content in a diet, should be approximately twenty to twenty five percent on a dry matter basis. (Cooper 2003). Protein is a major component of a raptor’s diet. It is broken down by the digestive enzymes in the gut. There are twentytwo amino acids; twenty of these amino acids are deemed essential; the remainder of these amino acids can be produced by the raptor’s other food components (Chitty 2008). The energy from protein is used for tissue growth and repair and should be from fifteen to twenty percent basis of a sound diet (Cooper 2003). The limiting factor of protein is the quality and type available in the diet. Deficiencies in protein are rarely seen if the raptor is eating a good quality whole carcass diet. All the essential amino acids are often available. Failure to process and absorb the protein from gut disease, parasites or metabolic issues may result in temporary “deficiency” which is evident by stress (fret) marks in growing feathers. A diet based on good quality protein, is preferred for optional growth and earlier fledging of juvenile raptors (Forbes 2000). Water is often an overlooked essential nutrient for life. Many falconers feel that raptors receive their water from their prey. Yet all raptors drink water and fresh clean water should be provided on a daily basis. An open dish of water encourages both drinking and bathing. Water intake can be enhanced by defrosting frozen food items in a warm water bath prior to feeding. All water containers should be cleaned to decrease protozoa or bacteria build-up. Either use hot boiling water or a disinfectant (Cooper 2002). continued on page 30 2012 The Imprint 29 NUTRITION & TRAINING continued from page 29 Micronutrients are the smaller building blocks of a sound diet, consisting of vitamins and minerals. Calcium, phosphorous and Vitamin D are readily available from a whole carcass food source with the bones included. Ideally, the ratio of calcium to phosphorous should be a 1:1 or better still a 2:1 ratio. To absorb calcium from the gut and to regulate calcium levels in the blood stream, the raptor needs Vitamin D which is in its active form as Vitamin D3. The Vitamin D3 is available in both active and inactive forms frokm their prey species. To obtain Vitamin D3, the raptor needs at least forty-five minutes a day of natural sunlight or UV radiation. Inactive Vitamin D3 is excreted from the preen gland, spread onto the feathers which is than activated by the sunlight and re-digested by preening (Forbes 2000). Imbalance of calcium and phosphorous can be either attributed to a poor diet in calcium levels or from lack of sunlight or preening which decreases the amount of calcium absorption into the tissue. Deficiencies will result in reproductive failure (soft shelled eggs, egg binding) rickets in young birds to tremors or weakness usually in breeding females. Over-dosages of calcium are often unlikely since the excess calcium will be excreted. However, over-dosages of active Vitamin D3 from zealous supplementation can cause excessive calcium absorption and mineralization of soft tissue (such as the kidneys) (Chitty, 2008). Fat soluble vitamins are Vitamin A, E, D and K. All others are water soluble vitamins. Vitamin A is often available in an uneviscerated carcass or day old chicks with yolks remaining. Up to 90% of Vitamin A is stored in the liver of the prey, and to a lesser extent in the fat (Cooper2002). The vitamin is needed for vision, skin integrity, disease resistance and growth. (Forbes 2000). A diet deficient in Vitamin A can be seen with weight loss, failure to grow, poor hatch rates and bumble foot (Hiedenreich 1997; Cooper 2002). Vitamin E is an important antioxidant which is stored in the body fat of the prey. Animals cannot synthesize Vitamin E which can be easily destroyed if the carcass fat turns rancid. The body organs of the carcass should be left in, especially blood and liver. There has been much thought that day old chicks have inadequate levels of Vitamin E. However, if the yolk is left in, day old chicks and rats can provide a high level of Vitamin E; even in excess of these provided by vitamin enhanced quail. (Forbes and Flint 2000). Deficiencies of Vitamin E can result in decreased libido of the male, decreased fertility and hatch ability of eggs, splayed leg and heart disease (linked to white muscle disease) (Chitty 2008; Cooper 2002; Forbes 2000). The primary role of Vitamin K is for clotting of the blood, and it is synthesized in the body by gut bacteria. Deficiencies are rare but they can rear with long term antibiotics use or coccidiostats and parasitic control that in turn can kill off the bacteria in the gut. It has been suggested that probiotics may have a beneficial role in re-establishing the beneficial gut bacteria. (Forbes 2000). The major water soluble vitamins are the B vitamins which 30 The Imprint 2012 are obtained from good quality whole prey. Only a few of the more important B vitamins (B1, B2, and B6) will be discussed here. Vitamin B1 (thiamine) deficiencies may occur with fish eating birds fed thawed frozen fish or from the inability to absorb or process thiamine (Chitty 2008; Forbes 2000). Rapid thawing of frozen fish and vitamin supplementation may prevent deficiencies (Cooper 2002). Vitamin B2 (riboflavin) is released from the liver of the prey. Deficiencies of Vitamin B2 had been reported with very young chicks with curled toes (Chitty 2008). Vitamin B6 (pyridoxine) is essential for protein metabolization and the formation of haemoglobin, or the pigment found in the red blood cells of the blood stream that carry oxygen around the body (Chitty 2008). Deficiencies of Vitamin B6 can be connected with anaemia, poor feathering and growth abnormalities. Excessive freezer storage will deplete the levels of all Vitamin B in food sources. It has also been reported that over- supplementation of Vitamin B6 given in multi vitamin can cause sudden death in falcons (Chitty 2008). Various Available Food Sources Wild Caught Prey One alternative to the use of free hunting prey is to use road kill or rifle hunted prey. However, these food items can be contaminated with rodenticides or lead. Even head shots of quarry, can have lead fragments scattered throughout the body. Infectious agents such as trichimonas (frounce), salmonella, E-coli, avian influenza, and herpes virus can all be transmitted to the captive raptor. Road kills (hit by car prey items) may also have been in a diseased state before they were killed. Raptors should not be allowed to fully feed up on prey items which are caught while hunting. A smooth trade-off should occur once the raptor has removed either the feathers or the fur; then the carcass can be thoroughly inspected. Any liver abnormality at all should cause serious concern such that the carcass should be condemned as a food item. Day-Old Chicks Day-old chicks (DOC) are the very staple in many raptor diets. They have also gotten a lot of bad press in the past. During a survey conducted at the Ontario Hawking Club (OHC) meet in London, Ontario, November 2008, DOC was considered the lowest of importance when compared to other various food groups (quail, chicken, rat, mice, rabbit and pigeon). Before the Forbes and Flint study in 2000, DOC were thought to be too high in fat, low in calcium and capable of transmitting E-coli and salmonella. Good quality DOC with the yolk sac feed intact has been found to have good levels of protein, fat soluble vitamins, calcium and phosphorous. DOC also has less fat than commercially raised rodents (Forbes and Flint 2000). Dr. David Bird, a professor at the University of McGill in Montreal Canada, has successfully bred and maintained a research colony of 100 kestrels for over thirty years. He has fed the birds exclusively day old chicks (personal communication). However certain species, i.e. Merlins, if fed exclusively DOC have been reported to develop a disease condition called fatty liver syndrome (hepatic lipidosis) (Forbes 1993). If calcium levels need to be increased, Ontariohawkingclub.org DOC can be coated with a calcium supplement with either bone meal or a veterinary calcium product (Cooper 2002). The problem with DOC is that they can be messy to feed and material can accumulate under the talons and develop a red pea like swelling. If this swelling is left untreated, it can lead to a nasty bone infection called osteomylitis (Chitty 2008). Three to Four Week Old Chickens DOC are often allowed to grow for a few weeks and then killed or fed live to raptors. The young chickens can be supplemented with vitamins and are a favourite with breeding falcons. At this age, the yolk sack has been reabsorbed by the body and the bones have ossified (hardened) with more calcium (Forbes 2000; Chitty 2008). Most respondents of the OHC survey classified young chickens as the second lowest ranked food group that a falconer could fed their captive raptors. Quail Quail has always been thought of as the best food source that a captive raptor could eat. The survey of OHC ranked quail as the number one food source. If quail is being fed, it should be killed around the six to eight week mark. At this age, the bones have been allowed to harden with calcium. Older quail that has been culled for various reasons may have been medicated, spent or depleted of vitamins. Caution should be used if using older quail as a food item (Heidenreich 1997). Female quail have consistently higher levels of nutrients and lower fat content when compared to males. At sixteen weeks, female quail had twice as many nutrients than males of the same age (Forbes 2000). Quail can have low levels of Vitamin E and cause deficiencies with breeder falcons. The Peregrine Fund facility at Boise Idaho had found that by using raptor raised Vitamin E enhanced quail hatchability and reproductive rates improved. However, DOC according to Dr. Neil Forbes has a greater Vitamin E level than enhanced quail. (Forbes 2000). Rats Rats are naturally high in Vitamin E and at a young age they have very high vitamin content. A good arrangement of using rats, DOC and quail for breeding has been made by Dr. Neil Forbes (Forbes 2000). Feeding rats to captive raptors does decrease the transmission of avian disease to the birds. If you are feeding rats to smaller hawks and falcons, you will need to skin and decrease the portion size. The fur and skin can be quite thick and difficult to break into. Larger rats can have a higher fat content and can be less suitable in nutrition than small and medium rats with eyass and breeders (Chitty 2008; Forbes 2000). Eviscerating the thawed frozen rat has been suggested due to bacterial contamination of the gut, the heart, liver and kidney (Chitty 2008). The OHC survey ranked rats as number one and two as a food source for falconry birds. Those who were short-wing falconers in the OHC survey ranked rats higher than long-wing falconers. Mice Mice are an excellent source of protein and calcium but can be quite expensive to buy. When compared to rats, many raptor keepers find mice easier to raise in home-grown colonies than rats. The mice at older ages can also be very high in fat (Chitty 2008). The OHC survey ranked mice closely behind rats. Hamsters and Guinea Pigs Hamsters have little advantage over mice (Chitty 2008). They do have thin skin, a little fur and with their smaller size, they can be fed whole to smaller raptors; but they can be expensive (Forbes 2000). Guinea pigs can be a good food source and economical for their size. They, however, have a long digestive tract which raptors are not fond of eating and can lead to a very dirty aviary when left behind. Evisceration of this long digestive tract is needed (Forbes 2000). The fur of guinea pigs can be quite loose and can cause an excessive amount of casting material and gut impaction. Skinning of the guinea pig is needed prior to feeding (Chitty 2008). Rabbits and Hares Both rabbit and hare are excellent sources of calcium and protein and are quite low in fat. Hare can be a richer meat to feed. The gut can be quite long and should be removed prior to feeding. The bones can be quite long and if left in their natural state can cause obstructions. For calcium availability it is best to pulverize the long bones and knuckles (Chitty 2008). Wild caught rabbits and hare can have liver flukes and tuleremia (a human zoonotic disease). The body cavity, especially the liver, should be carefully scrutinized before feeding. Whole Beef, Horse and Pork Beef is excellent in protein but is quite poor in calcium phosphorous. No amount of supplementation will improve this (Chitty 2008). Large joints can be fed to eagles and vultures but to improve the calcium phosphorous ratio, the bones should be pulverized before feeding. Horse and pork have been suggested to cause gout with birds. All processed meats (i.e. sausage, bacon) should be avoided. Feeding bacon has been linked to toxicity (Chitty 2008). Fish Fish eating birds, osprey and fish eagles enjoy fish and it should be part of their diet. However, they can do rather well on a diet based on mammals. Frozen fish should be defrosted in boiling water and it has been suggested to add B vitamins (Cooper 2000, Chitty 2008). Ocean fish contain enzymes that can inactivate the B vitamin thiaminase which can lead to this vitamin deficiency (Cooper 2000; Forbes 2000; Heidenreich 1997). Pigeon Pigeon is still being used as a staple for captive raptors’ diets. With the OHC survey, a third of the survey group still feed pigeon on a regular basis. Most falconers feel that freezing continued on page 32 Ontariohawkingclub.org 2012 The Imprint 31 If supplementation is to be used it is advised not to use supplements on a daily basis nor as a substitute for a poor diet. NUTRITION & TRAINING continued from page 31 the pigeons and/or feeding only the breast meat prevents the raptor from getting trichimonas (frounce) (Personal communication at the OHC). Although a good source of nutrition, the meat can still be contaminated with trichimonas and/or with avian viruses. The majority of free-ranging pigeons carry herpes virus which is transmittable to captive raptors. Other diseases often carried by pigeons include New-Castles disease, Avian Tuberculosis, Salmonella, Chlamydia and Avian Influenza. All these viruses are not inactivated with any length of domestic freezing at all. However, the OHC survey ranked pigeon near the top of the list to feed. Supplementation Today most people supplement their diets with vitamins, minerals or any combination of the two. Although our varied and nutritious diets are quite capable of sustaining our level of heath, most feel further supplementation will improve and enhance health. Some benefits are attained with supplementation use, but most are subjective. So it is quite natural that a lot of us will feel that supplementation will enhance the quality of life and performance of our captive raptors. Most of the OHC survey group have used supplements and are using an array of supplements ranging from Vita-hawk, Nekton S, Nekton E and bone meal. They feel that supplements do enhance the health of their captive raptors. If supplementation is to be used it is advised not to use supplements on a daily basis nor as a substitute for a poor diet. Many strongly advise that with a good quality varied diet, supplements are not needed at all (Forbes 2000; Fox 2000; Cooper 2000; Chitty 2008). It has been suggested that at certain times of stress, (breeding, moulting and possibly hunting) supplements may be used and could benefit the raptor (Chitty 2008, Fox 2000). Giving supplements can lead to two very serious problems. Firstly, supplements should be formulated professionally and specifically for raptor use. If a supplement for a non-raptor is used (i.e. from another species such as parrots), the supplement may be incorrectly balanced which can lead to an excess of one vitamin (usually the fat soluble vitamins) competing for and excluding other important vitamin absorption. Secondly, there is a problem of inaccurate portion control. Human nature sometimes clouds our judgement and a “do good attitude” may cloud our common sense. If one pinch is good then two pinches of the supplementation will probably be thought to be better. It is very important to follow the guide-lines for duration and amount that the vitamin suggests you use. (Forbes 2000). The supplements should be directed towards specific requirements at specific times (i.e. growth/rearing, breeding, moulting). The best supplements are ones which have been formulated specifically for raptors and have had some form of scientific research. Vita-hawk, for example, has been trialed on a control population for safety. It was backed by serial blood sampling that followed the effect the vitamin had at the normal and at exceedingly high levels of supplement given to a population of Red-tail Hawks (personnel communication with Dr. Bill Ferrier). Of course, during periods of stress, the basic feeding should be increased paying particular attention to protein quality and quantity (Chitty 2008). Many see improvement in breeding, moulting, growth and performance; however, could we be seeing improvements if we improved on a poor quality diet. Growth and rearing could obtain a benefit from additional calcium vitamin D3 and a fat soluble vitamin mix. Supplementation of calcium, vitamin D3 and vitamin E at least one month before breeding can both benefit male and female raptors. During moulting, a vitamin mix consisting of the essential amino acids and fat soluble vitamins (especially vitamin A) may decrease the duration of the moult and increase feather quality. Probiotics may be used to decrease the harmful bacteria in the gut which may become more plentiful at times of stress such as manning or transport. Since the raptors gut is unfermenting it is unclear what role probiotic use may indeed do for the body. Although, they indeed seem to cause no harm and the electrolyte solution that is carried with the probiotic powder may help as well. The use of rangle, the deliberate feeding of stones, is thought to cleanse the digestive tract of fat leaving the bird hungrier and keener to hunt (Fox 1995 and 2000). This practise may be more problematic than beneficial (Chitty 2008). Practising the use of rangle may cause serious gut damage or obstruction and should be avoided. It is debatable whether it indeed helps the bird’s digestive tract (Chitty 2008; Cooper 2002). In the Middle East, a dangerous practise of giving falconry birds ammonium chloride to cleanse the digestive system has resulted in a number of toxic deaths of raptors and should be avoided (Chitty 2008). continued on page 34 32 The Imprint 2012 Ontariohawkingclub.org Chicken Egg FOOD TYPE CATEGORY AGE SEX SAMPLE SIZE PREPARATION METHOD No Shell DOC Strain 1 1 day Male DOC Strain 2 1 day Male DOC 1 day Male DOC 1 day Male Whole DOC 1 day Male 200 Skinned DOC 1 day Male 200 De-yolked Quail (Male) 6 weeks Male 3 Plucked Quail (female) 6 weeks Female 3 Plucked 6 weeks Mixed 18 Quail 65.1 65.6 67 Moisture (%)Gross 75.3 72.4 73.6 75 76.1 77.8 78.5 Energy (kcal/kg DM) 14700 6020 6000 6100 6162 6000 6042 0.8 62.2 24.2 7.4 1.36 1.0 1.1 62.5 23.4 7.1 1.24 0.94 60 28.1 7.1 1.2 0.9 59.2 26.9 8.1 1.4 0.9 2.8 69.3 20 8.8 Crude Fibre (%DM) Protein (%DM) Lipid (%DM) Ash (%DM) Calcium (%DM) Phosphorus (%DM) Trace 0.9 0.4 72.4 22.6 7.5 Quail Vit E+ 7 weeks Mixed 100 Plucked 66.6 5565 64.9 33.2 9.6 71.6 28.3 12 47.4 25.8 10.3 3.8 3.3 58.7 27.8 13.5 19.6 Protein (g/100g) Nitrogen (g/100g) Lipid (g/100g) Ash (g/100g) 12.5 17.3 14.9 10.02 5.4 1.8 4.3 1.9 Vitamin A-Retinol (IU/100g) Vitamin B1-Thiamine (mg/100g) Vitamin E-Alphatocopherol (IU/100g) 634 496.7 363.3 0.06 0.06 0.07 14 1.6 1.06 40.7 21.4 Ca:P ratio 0.28:1 1.36:1 1.32:1 Calcium (mg/100g) Phosphorus (mg/100g) Copper (mg/100g) Iron (mg/100g) Magnesium (mg/100g) Manganese (mg/100g) Zinc (mg/100g) Sodium (mg/100g) 50 178 0.014 1.44 10 0.024 1.1 126 FOOD TYPE CATEGORY AGE SEX SAMPLE SIZE PREPARATION METHOD Rat Weaner 5 weeks Mixed 200 Moisture (%) 72.5 Gross Energy (kcal/kg DM) 5756 Crude Fibre (%DM) Protein (%DM) Lipid (%DM) Ash (%DM) Calcium (%DM) Phosphorus (%DM) 2.9 59.6 25.5 10.5 0.34 3.19 0.34 3.19 0.06 3.63 0.06 3.63 Rat Rat 63.4 34.9 7.5 1.49:1 1.5:1 775 521 0.264 5.23 36 <0.1 2.96 370 Rat Mouse 11 weeks Mixed 75 Eviscerated 12 weeks Male 3 65.6 68.3 66.9 5780 6305 2.4 62.8 22.1 10 2.06 1.48 1.3 62.1 31.5 6.6 11 weeks Male 64.3 1.3:1 Mouse 64.4 23.7 9.2 6 weeks Male 3 Plucked 44.8 41 10.3 2.3 1.5 2 56.7 26.9 9.5 1.94 1.4 Ca:P ratio 1.21:1 Calcium (mg/100g) Phosphorus (mg/100g) Copper (mg/100g) Iron (mg/100g) Magnesium (mg/100g) Manganese (mg/100g) Zinc (mg/100g) Sodium (mg/100g) 1010 838 0.847 6.74 59.5 0.92 3.73 254 Ontariohawkingclub.org Chicken 42.7 46.5 7.8 1.7 1.2 0.02 0.25 4.33 Chicken 1.5 58.9 29.9 9.7 7.44 0.45 5.89 Mouse 1.7 56.1 24.9 10.4 2.38 1.72 0.21 0.13 4.3 24.7 0.29 3.5 Mouse 5.7 0.29 7.14 66 5930 13533 5930 4470 0.18 4.79 30.2 <0.1 2.14 114 0.302 11.24 75.3 0.85 5.43 6900 65734 2286 0.266 8.5 57.9 0.66 5.5 2140 1390 0.48 11.1 74.8 0.417 3.88 204 6500 4000 1.33:1 4361 5923 816.7 1.39:1 3286 5840 Vitamin A-Retinol (IU/100g) Vitamin B1-Thiamine (mg/100g) Vitamin E-Alphatocopherol (IU/100g) 10.1 1.54:1 66.5 9.9 3.2 15.6 4.5 67.7 11.3 2.1 1.33 7.93 64.4 7 2.9 21.05 4.16 66.9 19.5 3633.3 0.18 64.9 19.7 9.6 9010 Skinned 16.4 6824 6644 12 weeks Mixed 200 Protein (g/100g) Nitrogen (g/100g) Lipid (g/100g) Ash (g/100g) 0.31 3299 1.17:1 680 581 0.268 5.57 33.1 <0.01 2.89 371 Mouse 9.3 4.5 67.7 64 47.2 10.4 0.85 5.9 1.38:1 3208 0.38 7.64 43.2 0.53 4.4 0.8 8.46 0.41 4.77 1.51:1 2110 1400 0.549 13.3 72.2 0.709 4.87 273 1.2:1 1.5:1 1.39:1 2455 0.45 4.91 0.3 5.28 0.27 9.76 53.6 1.1 7.41 2012 The Imprint 33 Guinea Pig FOOD TYPE CATEGORY 10 weeks AGE Male SEX 3 SAMPLE SIZE PREPARATION METHOD decapitated Sparrow Pigeon Pheasant Crow Rabbit Hare 11 Plucked Lean Lean Lean Lean Lean 68.38 72.2 72.4 69.6 74.2 74.8 Gross Energy (kcal/kg DM) 5393 6100 5520 5780 5890 Crude Fibre (%DM) Protein (%DM) Lipid (%DM) Ash (%DM) Calcium (%DM) Phosphorus (%DM 0.43 64.58 15.93 10.62 2.94 2.35 20.7 0 8.6 5 13 14.8 11.3 14.4 Moisture (%) 69.3 58.9 45.4 8.9 Washed 819 20.7 14.4 5.7 4.2 1.25:1 0.05:1 0.08:1 1.26 59.2 30 1.14 30 660 40 490 1999 2.98 Ca:P ratio Calcium (mg/100g) Phosphorus (mg/100g) Copper (mg/100g) Iron (mg/100g) Magnesium (mg/100g) Manganese (mg/100g) Zinc (mg/100g) Sodium (mg/100g) Beef 1149 Protein (g/100g) Nitrogen (g/100g) Lipid (g/100g) Ash (g/100g) Vitamin A-Retinol (IU/100g) Vitamin B1-Thiamine (mg/100g) Vitamine E-Alphatocopherol (IU/100g) Beef 2946 0.6 5.19 63.7 0.66 6.44 (Tables taken from BSAV Manual of Raptors, Pigeons and Passerine Birds, 2008, Permission by Dr. J Chitty) NUTRITION & TRAINING continued from page 32 Fitness and nutrition Being fit suggests being ready to perform a specific job. By training for a specific job, the hawk will have physical pressure brought upon them. Fat stores will be gradually decreased and muscle will gradually increase. A sound high-quality diet will be limited in amount and time frame when it is available. Falcons that are required to chase their prey great distances must be in shape for the strenuous activity and have the endurance of a marathon runner. Game falcons that ring up and perform a deadly stoop must be built more like a body builder with plenty of weight to perform a savage blow to its prey. Accipiter’s and Harris’ Hawks are sprinters which need both endurance and power to pursue their prey in long deadly sprints (Fox 2000). To understand fitness we must also understand what is occurring in the body and how it functions under physical stress. To function at peak performance, a body needs a good blood supply to flow to the muscles bringing oxygen and nutrients for energy and taking away the waste by-products (i.e. lactic acid, heat, carbon dioxide and water); thus the muscles may perform their task and not seize up. The seizing up of the muscles results in muscle fatigue. The muscles can also fatigue when 34 The Imprint 2012 the body depletes its reserves of glycogen from the liver. When all glycogen stores have been utilized leading to fatigue and exhaustion, the body will require a longer time to recuperate, often lasting several days before demands can be placed on it for training or hunting. The body has two main types of skeletal muscle fibre, red muscle and white muscle. Red muscle is for endurance and has fast and slow twitch fibres. Red muscle has a higher need for oxygen and a lower need for glycogen. (Fox 1995). It is used for power and is found more commonly in long flight birds (i.e. racing pigeons and migrating birds). White muscle is used for sprinting and is required for short bursts of speed and power. Birds such as chicken have white breast muscle for short fast bursts of flight and red muscle in the legs for long walking physical activity on the ground. Rabbits, on the other hand, have mostly white muscle in their major skeleton muscle groups and are sprinters, whereas, hares are built with red muscle for long endurance runs. Aerobic training is often done while oxygen rich blood is capable of delivering its fuel to the muscle such that oxygen suffers no debt. If the muscle is working too hard such that the demand for oxygen cannot be adequately supplied to the muscles, the muscles are now working in an oxygen deprived environment called anaerobic training. This anaerobic stress Ontariohawkingclub.org Ontariohawkingclub.org near the “fit not fat” weight (Fox 2000). If the hawk is flown fewer than 24 hours, it may stoop to the lure or do jump ups but may not be keen enough to hunt. Larger hawks are flown in combination with an appetite and weight system. The larger hawks also need more attention to their weight and may hunt well with one weight but refuse with another. Small hawks are more appetite responsive and because of their very high metabolic rate the weight must remain more constant and not be allowed to have rapid weight reductions. All birds will have a level of background fitness before starting any fitness training. If the hawk is kept free lofted in the mews, just the simple flight between perches will elevate the fitness level before training is started. Once the hawk is tethered, it should only be for a short time frame and a daily exercise routine could be woven into the hawk’s physical activity for the day. Line tethering on a cable or a free lofting can help the bird achieve its’ background level of fitness. Any tethering of the bird should be kept at a minimum and be used for specific purposes. A raptor is certainly motivated by its’ stomach but learns through a series of repetitions and positive associations (Mc Elroy 1999; Fox 2000). There is quite an array of different training methods used and developed for falcons and hawks. Some of the more common and traditional methods include jump ups, the swing lure, kits and balloons. All of these continued on page 36 Illustration by Tom Goldsmith can only be maintained for a short duration before lactic acid builds up and fatigue quickly sets in. Fitness training is mostly done in an aerobic environment where the blood flow to the muscles is improved and the onset of fatigue and the time for recovery is reduced. High levels of exercise, such as sprints, push the body into the anaerobic level and are only used in confined exercises. Once the moult has finished, the hawk will need to have the right amount of muscling, little or no fat and a good appetite. This condition will ensure that the hawk will fly strongly and predictably. There are three ways of assessing the overall condition of a bird: 1) the weight of the bird, 2) the feel of the pectoral muscles and 3) its behaviour out of the mews. It goes without saying that a good quality gram scale is what is needed for weight monitoring and charting. As the bird’s condition improves, the muscling along the keel will thicken up. It is probably important to check the deep pectoral muscles in the armpit area under the wing as well. If the hawk is either too thin or too fat, the behaviour can be very similar. A hawk which is unresponsive and unmotivated towards training and prey may be out of condition. To decrease the fat, you need to decrease the input energy (food) below the amount of output energy (exercise). Once fat is being lost, the weight will start to decrease. As the muscling is being built up the weight will start to rise. The loss and gain should occur at the same time so that the fitness is optimized. It is believed that once the hawk has reduced its weight by ten percent of its body weight, it can then be tamed and trained (McElroy 1996). The theory McElroy states “works nicely with peregrines but is too little weight reduction for accipiter’s, Harris’ and Prairie falcons”, and may require 12 to 14 % reduction for training. To accomplish this, the falconer needs to have some idea of what energy is being lost and what gain in energy is obtained. Different foods as we have seen have different energy gains. Fresh warm food is higher in energy than cold thawed food. Any fat in the prey can cause training setbacks; however, total fat restriction should not be practised but periodic feeds of controlled fat should be practised. As well, different animal parts of the prey can have different energy gains. Red meat is a good energy source; whereas white meat from rabbit can have the same nutritional benefit as washed meat. The hawk species (and size) will also dictate the amount of food and frequency the bird is fed. Small hawks like sharp-shins, kestrels, and merlins need to consume up to twenty-five percent of their own body weight in food a day. Medium sized hawks (i.e. Harris, Red-tail) need eight to fifteen percent and eagles need five to six percent. The smaller the bird, the more it needs to eat and more frequently. Eagles may eat only one to two days if given a large quantity and may not eat for several days after this large meal (Arent 2008; Fox 1995). If the fitness training drastically reduces the hawk’s food intake and does not increase the output energy, the bird will lose weight but will lose fat and not build the muscling it needs to hunt. A better way is to slowly decrease food intake and at the same time increase the exercise so that calories are burnt off. By monitoring the crop size, you can have an indication of when it is the best time to fly. For the bird to work it must be “So , I am out by the curb and this red Toyota pick up pulls up and a fricken Harris’ shoots out the passenger window.” 2012 The Imprint 35 Many falconers understand that a varied whole carcass diet suited for a wild falcon or hawk is still the mainstay when feeding falconry birds. NUTRITION & TRAINING continued from page 35 methods can be adjusted to suit both hawk and falconer. As the hawk progresses and becomes stronger, a slight variation of the exercise can further enhance the strength of the hawk’s fitness. Steve Layman has used a variety of strength training with his birds and if time is short for a proper training session or the days hunt did not meet the physical expenditure for the raptor, the conditioning exercise can be used to round out the days training (personal communication). The birds can become so conditioned to the training sessions that they will look forward to these varied training methods. Layman has said that birds doing 120 jump ups, then 120 jumps in a 20 minute time limit, flew longer and stronger such that the falconer and bird will have a deeper relationship which will improve the confidence that the bird will have in the hunt. Such novel training methods as restrained pursuits, yoyos, high-jumps, get the bird working and breathing harder, thus enhancing endurance and decreasing recovery time. Greg Thomas, the inventor of the “leash launcher” has taken the use of chains and long lead ropes and made them into a controlled strength training tool. By taking a long rubber tube leash and filling it with lead shot, Thomas has made a series of weighted leashes so that the falconer is able to adjust the weight that the bird needs to pull up on their jump ups. Thomas even has found that his Red-tails have better gripping power as they are forced to pull themselves and the weight of the lead up and onto the glove (personal communication). As the bird’s condition improves, different weighted lines can be added to increase the bird’s strength for short repetition just as a body builder would use a series of weighted exercises to enhance his/her muscular power. Both Layman and Thomas feel that by conditioning the bird in a more controlled manner, the bird can be kept at a higher body weight for hunting. They agree that the reserve the birds have will put them in a more determined and confident state in the hunt. To fully examine all of the different training methods is unfortunately beyond the scope of this paper. The reader is encouraged to explore new and more novel approaches to reaching the high level of fitness that one wants and desires to achieve before reaching the hunting field. In conclusion, raptor nutrition certainly needs to be studied in a more scientific manner. Unfortunately what we know has been studied in the field by biologists and little money is available for captive raptor nutritional studies. Many falconers understand that a varied whole carcass diet suited for a wild falcon or hawk is still the mainstay when feeding falconry birds. Day-old chicks, the staple of many diets, are very nutritious, good in energy and protein and have less fat than commercial grade rodents. A raptor formulated supplement although safe to use, should be used more during the stressful times in the hawk’s life (i.e. moult, hunting and breeding). Adding varied supplements should never be used to boost an inadequate diet. Fitness training, using traditional and non-traditional methods can produce a stronger and more powerful hunter. By becoming better fit, the raptor is maintained at a healthier and higher hunting weight which will bring longer partnerships and success both in and out of the field with our hunting companions.

The rain that continued throughout the day kept the 33 attendees inside the heritage school house, but the weather did little to dampen the enthusiasm and interest of the apprentices and would-be apprentices. Topics covered during the day were specifically designed to introduce aspiring new apprentices to a thorough introduction to the sport of falconry. Martin Gelenyse opened the day’s workshop with an overall intro into the art of flying raptors on wild game, general maintenance, and a discussion of the sponsorship program. Louise Engel followed the morning break with a summary of falconry birds and health concerns and how to avoid them. After a delicious spread of Burgers and salads put together by Bronco Bob and Colleen Simmons, Doug Wilson and Dion Thomson took over with discussions on hawking equipment that included everything from jesses and hoods to perches and telemetry . My own hen Red-tail, Roz was perched in the middle of the school room throughout the days discussions and drew particular interest in light of the recent wild take policy changes that will see many apprentices trapping a passage red-tail as their first birds. Attendees were additionally treated to an informative hands on session when Doug and Dion cast, hooded and jessed up two tiercel Harris Hawks for Carole Precious. As the participants readied to leave, I spoke with OHC member David Brand. David has a good grasp on the commitment involved and his attendance at the workshop was a testament to his commitment to learning. David added “ I know that falconry is a constant learning curve. Anything I can do to give myself a solid foundation for learning before I get a bird is time well spent.” The day proved to be a great success. As we cleaned up, Martin seemed happy that the event was as well received as it was. “Up until now those interested in falconry eventually came to a point in their reading and research that left them no choice but to jump into the deep end of the pool and see if falconry was for them. This event provides a shallow end of that pool where prospective falconers can test the waters to see if the falconry lifestyle is appropriate for them” commented Gelenyse. Louise Engle, who took on the task of organizing the first ever event of its kind in Ontario, wishes to thank the volunteers Dion, Doug, Tom, Martin and the ever helpful Colleen and Bob for their hard work and enthusiasm. Louise is looking towards the spring of 2013 as a possible time to make the next workshop available to interested parties and is looking for help in making that a reality.

Given the mass explosion of breeding birds in every major city in Ontario, why not here? Everything seemed to be in place: lots of pigeons and starlings and doves, with the city surrounded by farm fields, and high rise buildings to nest on. I have worked in and around this area for the last twelve years and have always kept an eye to the skies when driving through the city. I often find myself in elevator machine rooms – a great vantage point on the rooftops of the tall buildings where peregrines might be nesting. Over the last few years, I have seen the odd peregrine flying around the downtown Kitchener area but have never spotted a pair of birds sitting together. This spring we took over the contract at 55 King Street, so one morning in May I was driving into Kitchener to meet the tech who would be maintaining the building’s elevators and the superintendent of maintenance of the building. Still a couple blocks away, I noticed a peregrine sitting on the building. Then as I got closer, I noticed there was another falcon on one of the ledges way up high near the top. Could this be a pair of Peregrines finally nesting in Kitchener? How cool was it, going to be to have access to the roof to keep an eye on these birds! Since I was early for the meeting, I jumped into the elevators and took a quick ride up to the 12th and uppermost floor. Once up there, I wasted no time checking out all the sides, nooks and crannies for signs that the birds had chosen a ledge. Most of the falcons in Southern Ontario had laid eggs by now so I was hoping to see the female nesting. Upon examination, there were lots of feathers and a flicker cached in the corner. But no female sitting tight on her eggs. This was obviously a hangout for the 40 The Imprint 2012 male to do a little showing off to his lady friend and bring her food. So where were they nesting? I wondered whether the male had chased away an earlier suitor to the female or were these birds too young and would fail to nest this year. Although I looked for signs of them whenever I was around the area, I never spotted them on any of the nearby buildings. Then, about a week later, I spotted the two of them on the tallest building in the K-W area. I called Martin right away to let him know I had spotted these birds on the SunLife building so he could keep an eye on things as well. Fortunately, my company also does maintenance on the elevators in this building. So up again I went to the top floor to check things out. As luck would have it, the 19th floor was under renovations so I was able to check out all the ledges by walking the perimeter of the floor and looking through the large windows. I could see it was just like the other building; lots of feathers and small bird parts littered the ledges outside the windows. The problem for me at this building was that I didn’t have access to the roof. After a conversation with security, I did manage to get the keys, but they turned out to be the wrong keys. Oh well, I would just have to try again in a week or so as not to be too pushy about it, after all they are our clients. Before long, the building elevator tech knew all about the falcons because that was all I talked about while I was there. About a week later, I received a call from him. He and another employee had been working late with a crew installing new smoke alarms in the elevator machine room. There was a sliding door leading out to a balcony, and when one of smokealarm guys stepped out for a cigarette, the pair of falcons went off on this guy, screaming and stooping him. That was all I needed to hear to be certain that they had picked this rooftop as their nest site. I called Martin to share the news. He notified the MNR out of Guelph, and they wasted no time in contacting the Bentall property management group and Sunlife personnel to set up a meeting to get access to the rooftop. A few days later I was a part of the crew that made its way on to the roof to find the nest site. I checked the most likely spots but couldn’t believe where this young adult falcon had laid her eggs. The spot was so bad that one of the eggs had rolled across the roof only to be broken. We found one 18-day-old male sitting on the actual roof under a 10 inch wide by18 inches high I-beam. This I-beam was the only cover against the heat and rain. He was banded after a few days and a group of people came together to form a watch group, falcon-sitters if you will. I am still amazed this bird was alive. I was sure he would not survive to fly the skies above that tall building one day but he proved me wrong. Now the guesswork started as to when the young tiercel would make his first flight. The falcon watchers set up camp in the parking lot but were a week early before he finally launched. The probable reason this little guy took longer to get going was that he had no siblings to awaken his competitive spirit. He was an only child and sort of a stay-at-home spoiled child, since he was getting all the food and all the attention. Why leave and spoil a good thing? But nature and maturity finally got those wings moving. He did a lap around the roof to get some food, but even then did not do much else but work on his tan. The poor falconsitters would have been bored out of their minds, but at least the parents put in some decent airtime. The youngster finally left the nest site when his parents forced the issue, so hopefully the first wild peregrine raised in K-W will be spotted again next spring and in the years to come with a mate of his own. Ontariohawkingclub.org A Treatise of Modern Falconry By James Campbell 134 pp Edited by Walter Huston Published in 1773, Edinburgh Scotland Reprinted in 2003, Ranchester Wyoming USA Review by Yukio Yamada The preface page is a kiss-ass letter to the Earl of Eqlintoune by Campbell. This first page gives the reader a glimpse into the author’s character. The book has 40 chapters. Chapters vary from a half-a-page to four pages. Before publication, Campbell submitted the manuscript to a Reverend A. Gilles for his opinion. According to Joseph Haslewood, the editor of the 1810 reprint of The Book of St. Albans, Gilles added a lot of non-practical text to the Introduction that Huston gratefully omitted. Huston wrote in the Postscript that perhaps it wasn’t just Campbell and/or Gilles but also the wine talking. However, there were moments in the introduction where it comes alive. Take this passage: But firearms were at length invented; and this invention introduced as remarkable an alteration into sporting as it did into the art of war. The sportsman had hitherto drawn his pleasure from observing the various surprising turns of the chase or flight, and, when he obtained it, he was little mortified that the hare or woodcock made its escape at last from his hounds or hawk. This is the true idea which the sports of the field are qualified to afford; but the idea was gradually lost after guns were made of easy carriage and pointers trained to find out game. Sport came now to be confined entirely to the act of putting the game to death; and a man measured the liveliness of his diversion according to the animals he had slain. But, still, no birds were yet killed which kept in cover, and, therefore the game continued to be plentiful enough for every kind of sporting. This new idea, however, of sport made hawking decline; because a good marksman could procure more of this bloody sort of amusement from his gun than a hawk. Huston had the unenviable job of adapting an old text into modern English. He had to weigh through much scholarly text for the aficionados of 18th century English literature – probably most of it from Gilles. The book gives the reader a look into practical falconry of that time. Much has not changed and much has changed. One of the things that hopefully is no longer in practice is what the author calls “enseaming.” This barbaric practice involves forcing five or six pebbles down the throat of the raptor and then giving the bird castings (feathers and bones of small birds, or a wing of a larger bird or hare’s foot washed Ontariohawkingclub.org in water). The bird casts this out the next morning and this is suppose to cool the bird. OHC member and vet, Scott Craig said, “The thought was for the stones to move around and remove the mucous from the wall of the stomach (proventriclus and ventriculus), resulting in better absorption of food and to enhance hunting performance. It was believed that when the bird started to loose their field performance enseaming (by introducing rangle/ stones,pebbles) would clean/purge the bird out of this mucous build up. Mucous during the 1700’s was thought to come from a build up of heat, similar to what is understood in Traditional Chinese Medicine today. The mucous/heat needed to be cleansed periodically to ensure better performance.” Craig wonders how many birds lost their lives because of an intestinal blockage. He would not advise this and knows of no one practicing enseaming today. Speaking of “blockage” Craig also added “I would also be careful when giving large pieces of food to our bird as well. I have talked to other veterinarians who have had to remove bunny spines and large bone fragments from over zealous and hungry hawks”. Chapter 40 is “Of Diseases of Hawks and their Cure.” In 9773, medicines were made from herbs and other naturally occurring substances. Generally, the secrets of their applications were guarded as they were passed down for generations. It is not recommended that the reader use these remedies, it is clear that they were based on a long-standing knowledge of natural healing. It is interesting reading about the various healing properties of the ingredients cited. Interestingly Campbell does not mention using honey. Thanks to Huston, this book is a good read.

Glancing around, he sized up the landscape before lifting off to carry his quarry to a safe place to eat. He always carries. Carhawking always strikes me as more of an ambush than a hunt, but I have done it for years with my tiercel Harris’, Amadeus. I bought him in 2003 and have flown him on a variety of quarry, settling eventually on starlings that are taken ‘out the window’. This style of hawking hasn’t always felt like a good fit. My hawk has always carried- carried regularly and carried far. Perhaps it’s his own predisposition because he was the smallest one in the clutch, or possibly it was due to my own inexperience in his early training, but from the very beginning, I have struggled with this habit. A strong affinity to the lure has helped with retrieval a few times but was of little use when he carried his avian quarry into a large patch of poison ivy, or onto a small island in the middle of a marsh, or up into a drainage culvert, or under someone’s car (yes, they were in the car), or into a garage/barn/shed/ chicken coop, under a front porch or into a cedar hedge (“Excuse me ma’am, but just what are you doin’ in there?’). Well, you get the idea. I live in the country and don’t fly in urban environments if it can be avoided. But HH’s are known as the canine equivalent of the golden retriever and so far, inshallah, he has always come back safely. In fact, in an interesting combination of behaviours he has begun to carry and to come back, and now he flies right into the truck with his quarry. The 2012 season marks the third year that he has regularly carried his avian prey back into the truck, landing on my glove, and proceeding to pluck and eat on my fist. To say that this is convenient only begins to cover it. Not only have I given up crawling around in ditches and hedges 42 The Imprint 2012 trying to retrieve or even locate the bird, but for the first time we can regularly take multiple head of game. Furthermore, I have learned how to trade him off of his quarry in the truck and usually I’m able to stuff the starling, which is still alive-and-kicking, into a sparrow trap that I keep on the passenger side of the vehicle. The sparrow trap is covered with a blanket and these days, with any luck, each outing results in 3-4 live quarry for later consumption. I realize that I have reached a new low in lazy falconry- I don’t even get out of the truck on most days- but I’m willing to live with the shame. If I could tell you how to train a bird to do this, I would. But there has been no formal training and only a bit of luck and coincidence have resulted in this behaviour. The first time that Amadeus carried back to me was a couple of years ago. He had grabbed a starling on the open front lawn of a large country property and as I slowed the vehicle to a stop in front of the house, a dog in a kennel behind the garage began to bark. Amadeus hates dogs and he knows that when we are in the truck he is safe from them and that we move away from them quickly. So he looked around for a safe place to carry his lunch, because he always carries, and he saw the truck and came back to it. I happened to be inside and provided a convenient perch from which to eat. Needless to say, I was pretty pleased with this turn of events and I let him crop up completely. I really thought that we were on to something and I was very hopeful that this would be repeated the next time we were out. It turned out that I had to wait several weeks, although when it happened again the circumstances were very similar. Amadeus had once again taken a starling in a relatively open area when a red-tailed hawk suddenly screamed at him. I never did see the red-tail, but Amadeus came right back to the safest place he could find– the inside of the truck. Other than those couple of times, he continued to carry into cover and then jealously guard his prey from me as I approached. Tidbitting, bribery and sweet-talking were all meaningless to him. Once I could get close enough, I would toss down a lure and he would grab it, even if it meant letting go of his prey. I would then pick him up and walk back to the truck where he would finish eating. In 2010, the first starling of the season was taken on the lawn in an industrial area where there was no cover at all nearby. I leaned across the cab and out the passenger side of the vehicle, blew my whistle and waved my glove. He looked around, didn’t see any better offers, and flew directly to me. This time the behaviour stuck, and he returned with almost every starling that he took that season, enjoying his freshly caught meal while perched on the glove inside the truck. It makes for a lot of feathers in the cab. We only took singles last year, with a few doubles near the end of the season. I was adamant that he shouldn’t feel robbed, and was just happy not to have the drama of chasing around for him after each flight. Near the end of the season it occurred to me to try and trade him off and keep the starlings alive. These days we usually stop at four head when we go out. I end it there because I tidbit generously when he brings his quarry back to me, and after three large snacks I am concerned that his attention is fading. I don’t want to get too greedy about headcount and revert to smaller tidbits with the risk of having him feel robbed. I wouldn’t enjoy going back to looking in the cedar hedges for him- that might mean that I would have to get some exercise. With any luck Amadeus will continue to be my golden retriever for many years to come. Ontariohawkingclub.org
