Calgary Area Nestbox Monitors` Annual Report 2012
Calgary Area Nest-box Monitors
Annual Report 2012
Edited by Bill Taylor ([email protected]) and Don Stiles ([email protected])
Bluebirds Flying Higher
It was an excellent year for both target species, Mountain Bluebirds (MOBL) and Trees Swallows
(TRES). Although not the most fledglings ever for either species, we should be encouraged by our
efforts. There were 58 monitors or monitor teams who checked 4,333 boxes. The number of boxes
was down from last year (4,803) due to a number of retirements, and due to illnesses or absences
during the monitoring season. This accounted for 610 boxes, whose contents might well have raised
our totals to record numbers.
Much concern was raised during the summer about vandalized boxes. This affected 71 boxes. A
further 93 suffered predation from an unknown source. See the section on Nest Failures.
We have reorganized the presentation of monitoring results and trail details to reflect the quadrants
we monitor: north or south of the Bow River, and west or east of Highway #2.

The record for MOBL at 9 years old is one of our Calgary Area birds, 8051-94711 banded by Isabelle Orr
as an adult in 1997, and recovered in 2005.
Isabelle also recaptured this bird in 2004 as an 8 year old. As a 9 year old her eggs didn’t hatch.

Fifty-eight monitors or monitor teams cover 62 trails ranging from well south of Longview to Olds. Most
of the trails are west of Highway #2. Each “trail” averages 70 boxes and averages about 6 empty boxes
or about 8% of the boxes. Ideally we want all boxes to be occupied by our target species. Ones that
have been empty for several years should be relocated.
Four of the trails have not had their length (from first to last box) reported. Of the rest the average
length is 31 km. This would suggest that those average 70 boxes on a trail are placed slightly more than
2 per km. There is plenty of room for more boxes!
Nine monitors have not yet reported the round trip they need to cover their trails and return home. So
the average round trip for the rest of the monitors is 132 km. When you consider that most monitors
will likely visit their trails a minimum of 3 times (and some as often a 8 times), our monitors contribute
to the Alberta gasoline distributors to the tune of 19419 km worth of gas. If an average tank fill up is 45
litres…. Well you do the math! Our “hobby” is not inexpensive!
We are indeed fortunate to have such a large number of devoted monitors. The over 4,000 boxes we
have put in place in the last 20 years have contributed significantly to the growth in population of
Mountain Bluebirds and Tree Swallows in the Calgary area. We can all be
proud of our contributions. Our work, of course, is supplemented by at least
two other organizations in Alberta – the southern group centred in
Lethbridge, and a northern group NE of Red Deer. You may wish to check out
their websites:

The second (or late) MOBL clutches are about 1 egg smaller than the first clutch (4.6 against 5.4), but the
first broods have better success in hatching nestlings (86% against 76%). TRES clutches are larger than
MOBL clutches. MOBL first broods have the best results in fledging the nestlings (95% against 94 % for
TRES and second brood MOBL.) Terrific number of second brood MOBL this year!
Our total of MOBL fledglings was about 22 % higher than last year. It was a very good year for MOBL,
ranking 2012 as the 6th best year for MOBL. We hope it is the start of an upward trend. Although TRES
fledglings were less than 2011, it was still the 4th best year ever:

The following chart and table provide numbers of boxes, and fledglings for both target species.
The ratio (Fledglings to Boxes) is one measure of our success that we have used since we began
keeping records. (It could be misleading as the ratios do NOT indicate the actual sizes of the
average clutches. See page 8 for clutch sizes.)

Retiring Monitors
Ray Harris – Ray has been a very active monitor since 1982, first with the Lethbridge group and since 2007
with our group. For a few years, he was president of the North American Bluebird Society. He monitored
136 nestboxes on three trails north of Pincher Creek, one along Beaver Creek where his residence is, one
along Heath Creek and one at Maycroft along the Old Man River.
Ray Hummel – Ray’s trail was in the Drumheller area, mostly along roads on both sides of the Red Deer
River northwest from his residence in East Coulee. He began monitoring in 1989 and most years from
1992 to 2009 he had around 200 nest-boxes.
Rescue Effort
When Isabelle (Isy) Orr and Susie Spenst opened a bluebird nest they found a female bluebird that they
couldn’t lift off the nest to check for a band as usual. They found that the female was stuck in the nest
with baling twine wrapped around one of her feet. They were able to cut the twine loose from the bird
and then band her. They were surprised how calm she was. She flew to the next fence post and watched
them. The nest included a piece of plastic, thistle leaves and the baling twine as well as grass. As there
was poop on the eggs, she must have been trapped in the nest for a number of days, and the male must
have been feeding her. They cleaned off the eggs the best they could and replaced the nest with a last
year’s nest they had in their car.
There were 5 eggs to start with. Three of them hatched and then fledged OK, so Isy and Susie’s rescue
effort worked!

 Includes 1 EABL adult
Twenty-nine of our monitors also band their own birds. One of the great pleasures of doing so is
recapturing a previously banded bird. Often birds will return to the area where they were first banded,
but they do “wander” from time to time. That they can return so close – often to the same box – is
good testimony to the miracle of migration. Using visual clues by day, star patterns by night, and the
earth’s magnetic field as well (they have minute amounts of magnetite in their heads) they can retrace a
southward migration to the north in the spring. To become a bander speak to Bill or Don.
Occasionally we capture an Eastern or Western Bluebird, although they are not normally found in our
area. Melanie Rathburn (doing a long term scientific study) banded an EABL this year.
Banding Recovery Highlights 2012
Page 12
MOBL recoveries were up slightly at 197 compared to last year’s 186, and TRES recoveries were up at
236 from last year’s 217. Our main contributor for recoveries is Ron Reist, who monitors 412 nestboxes
east of Olds. He recovered 50 MOBL (18 banded as adults, 32 as young) and 108 TRES (106 banded as
adults and only 2 as young). See Table 1 – Summary of 2012 Recoveries for distance moved, whether
banded as an adult or young, and age distribution.
The term recovery is a generic term which describes when a bird with a band is found, whether alive or
dead. Almost all of the birds mentioned will have been recaptured alive and released.
Long Distance Bluebird Recoveries
8 long distance MOBL recoveries in 2012 are listed below. 4 were banded as young in 2011, 2 in 2010
and 1 in 2008; and 1 as an adult in 2011. Details follow:
2261-76529 was banded as a young in 2008 by Don Conrad S of Longview on Hwy 532 W of Hwy 22 and
recovered by Dick Stauffer W of Olds – moved 162 km (100 mi) N.
2231-83514 was banded as young in 2010 by Ray Harris north of Pincher Creek and recovered by Barry
Trakalo NE of Millarville – moved about 136 km (84 mi) NNW.
2431-96557 was banded as a young in 2011 by Nancy Rand SE of Black Diamond and recovered by Gwen
Tietz S of the Shell Pincher Creek Gas Plant – moved about 125 km (78 mi) S.
2261-75572 was banded as a young in 2010 by Ray Woods in the Elkton area W of Didsbury and
recovered by Shonna McLeod near Leighton Centre SW of Calgary – moved 96 km (60 mi) S.
2541-75704 was banded as a young in 2011 by Mary Jane Hunter in the Springbank area and recovered
by Ron Reist east of Olds – moved 89 km (55 mi) NNE.
2431-91991 was banded as an adult female in 2011 by Don Conrad on Hwy 533 SW of Nanton and
recovered by Ray Harris N of Pincher Creek, moved about 62 km (38 mi) S.
Mary Jane Hunter recovered two MOBL on Hwy 541 W of Longview, both banded as young in 2011, one
by Mike Truch SW of Nanton moved about 39 km (24 mi) NNW, and the second by Bill Taylor N of
Okotoks moved about 30 km (18 mi) SW.
Long Distance Tree Swallow Recoveries
2401-94155 banded as a young in 2011 by Marijke Jalink W of Millarville and recovered by Ron Reist E of
Olds – moved 125 km (77 mi) NNE.
2401-94579 banded as a young in 2011 by Dick Stauffer W of Olds and recovered by Bill Taylor SE of
Millarville – moved 110 km (68 mi) S.
2321-97408 banded as a young in 2009 by George Loades in the Priddis area and recovered by Dick
Stauffer in the Olds area – moved 110 km (68 mi) NNE.
MOBL Recovered Again
Page 13
Several monitors reported MOBL which had moved significant distances in 2011 or 2010 and then had
stayed in the same box or nearby in 2012. Five of those which moved longer distances are reported
below.
Bob Danner of Edmonton recovered 2291-35638 in 2011 twelve miles SW of Leduc. This bird was
banded as a young in 2008 by Ron Reist east of Olds and moved about 145 km (90 mi) N. Bob
recovered this bird again in 2012 in an adjacent box, 400 m away.
Dick Stauffer recovered 2231-14220 in the Olds area in the same box in 2011 and 2012. It was banded
as a young in 2009 in the Ponoka area by Murray Mackay and moved 108 km (67 mi) SSW to Dick’s trail.
Melanie Rathburn recovered 2291-35877 in her box K7 in 2010. It was banded by Dick Stauffer of Olds
as a young in 2009 and moved 102 km (63 mi) S. Melanie recovered it again in 2012 in the adjacent box
K8.
Diana Halladay recovered two MOBL in 2012 in the same boxes where she had recovered them in 2011
on her trail NW of Olds. 2261-84743 was banded as a young in 2009 by Shonna McLeod, having moved
127 km (79 mi) N. 2431-96221 was banded as a young in 2010 by Ron Reist, having moved 27.3 km (17
mi) WNW.
Oldest Birds
MOBL 1791-21984 was banded as a young by Barry Trakalo on June 13, 2004. It moved about 5.6 km NE
to Don Stiles trail in 2005, and then in 2006 it moved 3.6 km SW to Shonna McLeod’s trail in her box W2,
back towards where it was banded. It was found again in 2012 by Shonna in her adjacent box W1.
This makes it 8 years old, a good longevity record. We have only recaptured one 8 year old MOBL
previously.
TRES 1921-26238 was banded as a young in 2004 by George Loades in the Jumping Pound area. It was
found dead in the spring of 2012 by Susanne Maidment while checking boxes. “Due to the condition of
the body, it probably died late last fall.” This would suggest it probably died of old age at the age of 7.
We don’t have a record of previous recoveries of this bird, or the box number where it was banded, but
our records show it was banded in the same area.
TRES 1921-27810 was banded as a young in 2005 by Bill Taylor, making it 7 years old. He recaptured it
in the same box in 2008, 2010, 2011 and 2012.
Birds recovered on adjacent trails
Don Conrad and Kirk Davis recovered several of each others MOBLs. Don Conrad’s trail is SW of Nanton,
and Kirk Davis’s trail is W of Stavely. Kirk reports his statistics to the Lethbridge group. He took over this
trail from Brian Keeling in 2011. Don Conrad recovered 4 MOBL, all banded as young in 2010 by Brian
Keeling. These moved distances of from 8 to 12 km, mostly N. Kirk Davis recovered 3 MOBL banded as
young (2 in 2011, 1 in 2009) by Don Conrad. These moved distances of from 7 to 15 km, mostly S.
Birds banded as adults returned to the same box
Page 14
Ray Woods, Anne Weerstra, and Dick Stauffer all recovered three MOBL banded as adults which
returned to the same box where they were banded. Years when the birds were banded were RW 2011
– 1, 2010 – 2; AW 2011 – 3; DS 2011 - 1, 2009 – 2.
Andrew Holder recaptured three TRES, all banded as adults and all returned to the same box where they
were banded, one in 2009, one in 2010 and one in 2011.
Two Species in one box
Shonna McLeod banded MOBL 1431-73167 and TRES 1911-55787 as adults in 2011 in her box C41 in the
Priddis area. In 2012 both birds were also recovered in the same box. The TRES had taken over the
nestbox from the MOBL. This happens occasionally on Calgary area trails, but it is believed to be the
first time it has happened to the same two birds in the same box in two seasons.

Members of the Public
Treva Felzren found TRES 2401-94546 dead in a nestbox near Bentley. It was banded as a young in 2011
by Dick Stauffer SW of Olds. This bird moved about 83 km (51 mi) N.
Henk de Jonge found MOBL 2431-96566 dead, caught by cat “in front of barn at home”. It had moved
4.5 km NE from where it was banded as a young in 2011 by Nancy Rand SE of Black Diamond.
Tara Conroy found 2261-78875, a male MOBL dead on her deck on April 27, due to a window strike. It
was banded as a young in 2010 by Barry Trakalo, and moved about 10 km SSW.
Nigel Warren found a dead female MOBL at his acreage at Hwy 773 and 265 Ave on Sept. 15 due to a
window strike. It was a young of the year, banded by Barry Trakalo on May 27, 2012, and moved 5.3 km
(3.3 mi) NE.
Thanks to Don Stiles who keeps track of all bands issued, and all recoveries.

The above does NOT include those cases of House Wrens, House Sparrows, or Tree Swallows who may
have taken over a nest before original occupants fledged. (See chart below.)
Most of the “unknown predation” consisted of the bottoms pushed up and the contents removed. In
past years we have often blamed raccoons for this, but Ray Woods and others have suggested that
coyotes may well be the culprits. Those monitors who have screwed in the bottoms have noted that
the predation was less than before. Weasels will usually leave the corpses in the box. Cats will usually
leave the corpse near the box. We presume that the unknown predator has taken the edible nest
contents with him or her, as few monitors have recorded the presence of fledgling remains.
Weather was much more significant in the south this year than in the north. However, the north seems
to have more losses due to construction or fence removal. Do we need to write to our municipalities to
recommend NO such construction during May, June and July?
There were 56 House Sparrow nests and 144 House Wren nests – similar to last year.

The Predation/Vandalism Concern
Page 16
Donna Wieckowski: The next 11 boxes were tampered with. Either the bottom was removed and the
nests and eggs strewn on the ground or the bottoms were tipped up on their side and any nest was
tipped up too - if there were eggs in them we found them on the ground. I reset the nests in the boxes
that only had them tipped up inside the box so maybe the TRES can reuse them even though all the eggs
had fallen out. All the eggs were whole so, to me, that rules out predators.
Lyn Brown: Our trail is west of Hartell, which is north of Longview. Yesterday, out of our 49 boxes 13
nest have been tampered with/destroyed in the last 2 weeks. In one case the box had been ripped off
the post, but was still intact with (barely alive) babies. Lots of grass trampling both sides of the fence. In
a couple others the nests were sideways in the box, one with brand new hatchlings still alive.
Don Crane: Today I spent a lot of time visiting farmers, workers and the MD employees along my B.B.
route. As reported in mid-June many boxes had been ' vandalized' with the bottoms tipped up.
I talked with twelve nearby farm families about the style of box disruption. Not one had seen or found a
raccoon in the area, but two thought there was one sighted in Madden and another in Cremona many
miles away. Nothing proven. Chicken coops OK.
They said that they had never seen human vandalism on their property but some unusual quod tracks,
probably made by young fellows, were in ditches. No activity by those was seen near boxes.
Jennifer Hilborne: This was is the story I've put together on the destroyed nests. I was out on my trail
yesterday which is west and slightly north of Millarville, between Hwy 22 and 256 St.
A farmer was out haying and I asked about racoons - he hasn't seen any for about 3 years but he just
found a decaying bear in his field. All but one of the nests that were destroyed were around this field.
The week before I spoke to another property owner (corner of 224 St. and 302 Ave.) and he claims to
have had a cougar trying to get under his deck. There are what looks like long scratch marks and
splintered wood. A friend of his living near Priddis, did actually see a cougar coming down her driveway!
One last thing, I have seen quad tracks in a ditch but not near the destroyed nests.
Marijke Jalink-Wibrans: All farmers along our trail hate raccoons and will try to terminate them. The last
three were a question mark, it wasn’t done by a raccoon or coyote or human, we discussed it with
owners of the property where we have boxes along their drive way. Well, Diane saw a young Black Bear
in her beautiful garden and we knew who was the culprit!
These are just a sampling of many observations emailed by monitors. Thank you for all your comments.
I wish I could include them all! We have possible human vandalism, possible predation by raccoons,
foxes, cougars, bears. The most common suggestion was the coyotes may have learned to push up the
bottoms of the boxes. Screwing in the bottoms seems to be very effective:
Deb Nichol: I think because we screwed all the bottoms in, so we didn't lose any to predators early this
year!
