One of the most impressive antelopes found in Africa is the sable. Unfortunately, as a result of habitat destruction and poaching, it is also one of the most endangered.
As these antelopes age, their colour changes. The calf is born grayish-brown, blending in with the grass. As they age, its coat becomes a rich reddish-brown, with the belly, haunches and facial markings in greater contrast. At this time the face is largely white, with a wide black stripe running from the forehead to the muzzle and black stripes from the eye to the muzzle.
Once they reach maturity, the female’s colour changes and her shoulders and mane become darker. However, as the males become an adult their colour change is more dramatic — all parts that were red become black.
