Ardeotis kori, bird atlasing, bird monitoring, Kori Bustard, Namaqualand, SABAP2
The value of putting camtraps out for bird atlasing purposes or bird monitoring cannot be underestimated. The accompanying pictures are of a Kori Bustard Ardeotis kori. They were taken in an area where the bird would not have been observed easily. The vegetation provided enough shelter (though the pictures show the bare patch where we set the camera up) and the area is very flat – so the birds would either have flushed long before being observed. Or they would have taken to cover in the tall grass and shrubs.
At first I was a bit shy …
The pictures do not show the complete bird – but we have enough evidence of its presence in the area. If this bird was not picked up on the camtrap it would not have been recorded in the pentad (5′ x 5′ lat/long square) for atlasing purposes for SABAP2. Despite the fact that we had driven past the location of the camtrap frequently in the 5 days that we worked in the area.
Let me show a bit more of myself …
The pictures were taken east of Springbok in Namaqualand (Northern Cape, South Africa).
Aardwolf, Bushnell Trophy Cam, Cuddeback Attack, Karoo, leopard, Maanhaarjakkals, Namaqualand, Proteles cristata, Protelidae, strobe flash
The Aardwolf Proteles cristata mostly makes a good model for the camtrap. This may well be due to its foraging behaviour of walking slowly, standing still and listening intently and looking up with cocked ears. When it passes a camtrap within range, the photos are almost always good and clear. The colour pattern of these animals makes them good subjects to photograph both in black and white and colour. The two pictures were taken near Springbok in Namaqualand and Laingsburg in the Karoo.
The thick mane on the nape gave these animals their Afrikaans vernacular name. It is called Maanhaarjakkals (“mane jackal”) which is actually a misnomer as they are not related to the jackal at all. Although they are sometimes grouped with hyaenas they are not related to these animals. The Aardwolf is in a family of its own – Protelidae.
Aardwolf – Namaqualand
It is a nocturnal mammal living almost exclusively on termites – up to 300 000 of these creatures per night and as much as 420 kg per year. The dentures of this animal has adapted to this specialised diet so much that it cannot crush bones or kill anything larger than insects. The animals will dug into termite mounds and then lap up their prey with large amounts of the loose sand. Unfortunately some of these animals are killed in indiscriminate ways of hunting for problem predators.
The Aardwolf occurs widely across southern Africa. During the day they will sleep in burrows and at dusk they will start foraging. When they leave the burrow they will quickly move to the closest midden and there they may lose up to 10% of their body weight at once. The faeces has a sharp pine odour due to the high content of termite remainders and contains quite a lot of sand which is ingested with the termites when feeding. Another characteristic is the high number of termite heads that can be seen in the faeces. These middens are a telltale field sign of the presence of these animals in a particular area.

These two photos clearly demonstrate the difference between two camera types used in the field. The colour photo was taken with a camera (Cuddeback Attack) which employs a strobe flash (white light) to give colour pictures even at night. The white light (like the flash of a normal camera) can be seen by animals and it may pose some disturbance to animals. The black and white photo was taken with a Bushnell Trophy Cam with infrared flash technology of which the light cannot be seen by animals and therefore they are not disturbed. In certain instances the colour pictures are preferred by researchers to ID the individual animal in the field. Leopards for example each have a unique pattern in their spots and can be individually identified.
