Antelope: Bontebok

Bontebok (Damaliscus pygargus pygargus) and Blesbok (Damaliscus pygargus phillipsi) are separate subspecies of the Damaliscus pygargus.

Classification
Order: Artiodactyla
Family: Bovidae
Genus: Damaliscus

The Bontebok

{Resized by BGS}

The name bontebok comes from bont (Dutch) particolored and bok (Dutch) a buck. Bles (Dutch) a mark or blaze; bok (Dutch) a buck: alluding to the white blaze on the nose.

Bontebok stand 80 to 100 centimetres at the shoulder and weigh 50 to 90 kilograms. The Bontebok is a chocolate brown colour, with pure white buttocks and a white stripe from the forehead to the tip of the nose. Blesbok are reddish-brown with a pale brown buttock patch and the white blaze on the muzzle is broken by brown between the eyes.
The horns of Bontebok are lyre-shaped and clearly ringed they are found in both sexes. Average horn length is 38 cm.

Blesbok live in highveld where they eat short grasses, while Bontebok are restricted to coastal Fynbos and Renosterveld. They are diurnal, though they rest during the heat of the day. On hot days the herds characteristically orientate towards the sun with their head bowed.

Conservation Status
The bontebok is classified as vulnerable

You can find them in some areas very far from there natural cape distribution , as far as I am concerned this is totaly irresponsible as they can crossbread with blesbok which threatens the endangered bontebok due to genetic issues.

Bontebok shouldnt be allowed anywhere out there natural distribution areas , and blesbok into those areas .

Same goes for other similar species .

It looks like the one in the photo was right in the camping area


My picture was taken in the camping area of BBNP, do you mean the first pic, or Katja's?

Mine was taken in the camping area of BBNP too, so he is right, no matter which photo he meant. :D

i did some research on the bontebok feeding prefereance in bontebok national park and ill post it soon, but firstly the Damaliscus pygargus pygargus is a blesbok, the bontebok is Damaliscus dorcas dorcas and for interest ill post a link to the paper i submitted to UCT about their conservation status...

[edit: according to my literature that is, i have also seen bontebok described by other names and many believe that they are a sub-species, or race, resulting in worries about their interbreeding and loss of genetic seperation. A nice example of divergent evolution imo]

In the Field Guide to Mammals of Southern Africa, Chris & Tilde Stuart, 2001 they are classified as Bontebok Damaliscus dorcas dorcas, Blesbok Damaliscus dorcas phillipsi, but sources on the Internet claim these are their old names.
Bontebok are named Damaliscus pygargus on the ITIS standard report page and in the Wikipedia. In this article [pdf], the bontebok (D. p. pygargus) and blesbok (D. p. phillipsi) are classified as two subspecies of Damaliscus pygargus.

Foncusing it is.
