Defassa Waterbuck are large and handsome antelopes that are quite common along the Narus River in Kidepo National Park. They require fairly open grassland and they don’t stray far from water.
Any number of subspecies have been described but they fall into two groups. The more easterly group, Common Waterbuck, was the first described and given the scientific name Kobus ellipsiprymnus. Kobus is an African name given a faux Latin ending. Ellipsiprymnus is from Greek – ellipsi meaning ring and primnos meaning hind part. It was so named because of the white target on the animal’s rump.
The more westerly group was described as a separate species, Defassa Waterbuck, but where the ranges meet they hybridise readily and the two groups are now lumped in the one species. There is no white ring on the rear end of a Defassa Waterbuck. So it now has a scientific name celebrating a feature that it doesn’t have.


Only the males have horns and these are used in competition for access to females.

They are said to taste terrible which is quite an advantage when it comes to living with lions and human beings.
