Singita Kruger National Park Wildlife Report Nov 2015
Photo by Brian Rode WILDLIFE REPORT SINGITA KRUGER NATIONAL PARK, SOUTH AFRICA For the month of November, Two Thousand and Fifteen Temperature Average minimum: Average maximum: Minimum recorded: Maximum recorded: 19.6°C 33°C 15°C 40°C (67.2°F) (91.4°F) (59°F) (104°F) Rainfall Recorded For the period: 27 mm For the year to date: 183.5 mm Sunrise & Sunset Sunrise: 04:57 Sunset: 18:15 On the twenty sixth of November we experienced a spectacular electrical storm. We watched as lightning struck and set fire to the surrounding grassland. The cover photo was taken at dinnertime, from the lodge. How's that for Nature putting on a show! Our wildlife review for the month is as follows: Buffalo: The movement of buffalo has remained in an east-west pattern along the central area of the concession, and a large herd of around five hundred buffalo regularly cross south over our northern boundary. We often see other plains game like wildebeest and zebra trailing behind the herds as they make their daily trip towards the water. Photo Deirdre Opie Leopards: The Mahlangulene female was found in the northern parts of the concession resting in a tree. She had killed a female impala and unfortunately lost her kill to hyenas as she had left the carcass at the base of a tree. The Xhikelengane female was seen on a few occasions on our western boundary patrolling her territory. We also had great views of the Ndlovu male and a few unknown leopards. Photo by Brian Rode Cheetahs: The female cheetah and her four cubs have been the highlight for many of our guests. The cubs are becoming more adventurous. We spent many hours watching them chasing each other in and around trees. The cubs still have long fur on their backs that help to camouflage them. The mother had to move her cubs away from the central depression area where they were spending most of their time, as the Shishangaan male lions dominated the area for a few days. Photo by Barry Peiser Elephants: After a few millimetres of rain we watched as a breeding herd of twenty-five elephant carefully walked across the Dumbana rocks. They skilfully sucked up the fresh rainwater that was trapped in the rocky hollows. After quenching their thirst, the herd moved off into the grassland. On our trips to and from the airstrip we have seen big bull elephants feeding in the plains. Photo by Barry Peiser Lions: The Shishangaan males have been roaming in the central and northern parts of the concession. They were seen feeding on a giraffe carcass for a few days and we had great views of them chasing vultures away from the kill. The Shishangaan females and cubs are spending a lot of time near the diminishing waterholes. The females and cubs have full bellies and seem to be preying mostly on kudu and waterbuck. They were also seen trying to steal an impala kill from two leopards. The leopards were trapped in the upper branches of the tree until the lions lost interest and moved off. Both the Xhirombe pride and the Collared pride were also seen this month along the northern and eastern boundaries of the concession. Photo by Brian Rode Hyenas: Both the H6 clan and the Nyokene clan were viewed this month. The cubs at the Nyokene den-site are usually seen looking out from the entrance to their cave. The H6 clan has been very active and we have been privileged to watch the mother hyena suckle her cubs. The older cubs enjoy playing and chasing each other around the entrance to the den-site in the late afternoons.

These discharges result in sudden flashes of light and trembling sound waves, commonly known as thunder and lightning. Thunderstorms are associated with convective clouds and are often accompanied by rain or hail. Droplets of water form as warm air rises upwards, cools and then condenses. If there is enough instability in the air, the updraft of warm air is rapid and the water vapour will quickly form a cumulonimbus cloud (large anvil-shaped clouds). As the warm air continues to rise, the water droplets combine to create larger droplets which freeze to form ice crystals. As a result of circulating air in the clouds, water freezes on the surface of the droplet or crystal. Eventually the droplets become too heavy to be supported by the up-draughts of air and they fall as hail. As hail moves within the cloud it picks up a negative charge by rubbing against smaller positively charged ice crystals. A negative charge forms at the base of the cloud where the hail collects, while the lighter ice crystals remain near the top of the cloud and create a positive charge. The negative charge is attracted to the Earth's surface, other clouds and objects. When the attraction becomes too strong, the positive and negative charges come together or discharge (known as a lightning strike or lightning bolt). The rapid expansion and heating of air caused by lightning produces the accompanying loud clap of thunder. It is estimated that a lightning strike hits somewhere on the earth's surface approximately forty-four times every second. Thunderstorms are created by intense heating of the earth's surface and are most common in areas where the weather is hot and humid. Land masses therefore experience more storms than the oceans. Honey badger versus an African rock python Photos and article by Chantelle Venter We had just left a large herd of buffalo feeding in the plains and rounded a corner to find sand and dust flying everywhere. We saw a honey badger (Mellivora capensis) digging vigorously at the base of a dead leadwood tree (Combretum imberbe). He stopped briefly to sniff the air, and moved around to the opposite side of the tree to resume digging. To our surprise a large African rock python (Python sebae) shot out of a hole near the base of the tree to try and escape the claws of the honey badger. We watched the standoff between these two incredible creatures. The honey badger would try to make his move to catch the African rock python, only to be faced with the angry reptile's sharp teeth. The African rock python made a fatal error by trying to climb up a nearby shrub. The honey badger took full advantage of the python’s mistake, and managed to grab the snake behind the head. It proceeded to drag the large snake to a nearby shrub. The badger started digging a hole to cover its meal. We decided to call it a day and leave the honey badger to feed on its catch. Photos by Chantelle Venter Flap-necked Chameleon (Chamaleo dilepis) Photo by Barry Peiser and Article by Chantelle Venter The chameleon has specially adapted feet (zygodactyl) in order to grip branches as well as having independently movable eyes, allowing them to look in two different directions at once while searching for insect prey. Each eye can scan almost 180 degrees, with the only blind spots being immediately above and below the body. The chameleon’s brain switches rapidly between the two different images it receives, concentrating on each image for a second before moving to the other. Chameleons are able to change colour by adjusting a special layer of cells (iridophore cells) nestled within their skin. These adjustments affect how light reflects off their skin. The flap-necked chameleon is found throughout southern Africa and is one of the most widely distributed chameleon species occurring in coastal forest, bushveld and grassland savannah. They can be found in amongst branches of trees and shrubs as well as on the ground when they look for a mate or new feeding grounds. Female flap-necked chameleons are generally larger than the males and therefore out-compete them for favourable hunting grounds. The females usually act aggressively towards the males, but will allow them to approach during a short mating season. Besides its natural enemies of snakes and birds, the flap-necked chameleon has man to worry about. It is one of the most extensively exported chameleon species. It has therefore been listed on Appendix II of the Convention of International Trade in Endangered Species (CITES) and any international trade in this species is therefore strictly controlled and regulated by annual maximum export quotas. Without proper monitoring of the effects of harvesting them for the pet trade, the flap-necked chameleon’s population is at a potential risk of decline. .
