Waterbuck

There are two subspecies of this animal in Africa, the Defassa and the Common Waterbuck. The one on the picture above is a Common Waterbuck, a male relaxing in the morning sun. 

Appearance
The Common Waterbuck is a large antelope, weights about 200kg, with a shaggy gray coat easy to distinguish. The males have long horns, heavily ridged, diverging at the base and rising in a crescentic curvature. The female are similar to the male, but somewhat lighter and without horns.

The Common Waterbuck is easy distinguished from the Defassa by the funny white circle on the rump, the only antelope with such a pattern. 

Habits
Both species looks and behaves very similar. They lives in small herds, 5-25 head, with one single adult male. Woodlands and clearings are preferred habitats. Usually they lives near water where they also takes refuge in, but they may wander long distance from water to feed. They are grazers and feed on tender shoots and drinks freely. They do not migrate as their habitat has got cover and grass all the around the year. 

The Defassa is slightly larger than the Common Waterbuck and weights around 300kg. It  has an solid white patch on the rump instead of a circle.
