Waterbuck

Kobus ellipsiprymnus (Ogilby, 1833)
French: Cobe defassa
German: Wasserbock
Swahili: Kuru

Subspecies
K. e. defassa
K. e. ellipsiprymnus

Description
Total length: 2.10 - 2.74 m
Tail length: 35 cm
Shoulder height: 1.30 m
Weight: 250 - 270 kg
Gestation: 8 months

This large species has a coarse, shaggy coat, grey-brown to reddish. Like all Reduncinae only the rams carry long, heavily ridged horns. Ears are rounded with black tips and white insides. There are also white markings on the throat, around the nose and mouth and above the eyes. The defassa waterbuck has a white blaze on the rump.

Distribution
K. e. defassa: Eritrea, Sudan, Ethiopia
K. e. ellipsiprymnus: Somalia, Ethiopia.

Ecology
Appropriate to their name, they are always associated with water. They occur in small herds up to 30 individuals. Bulls have territories which they establish at five or six years of age. Waterbucks can also be identified by their musky scent. While other antelopes give birth to a single calf, there is a higher incidence of twins in waterbucks.

Conservation Status

IUCN Red List Category, ver 3.1:

- http://www.iucnredlist.org/apps/redlist/details/11035/0

Trend:
More than half the population survives in protected areas, with about 60% of Defassa in protected areas, and more than half of Ellipsen waterbuck in protected areas (plus 13% on private land). Important populations of the Defassa waterbuck persist in areas such as the Awash Valley and Omo-Mago-Murule in Ethiopia. Important populations of the Ellipsen waterbuck occur in areas outside this region.

European Collection Plan (2003): ...
RCP status: ...

Recommendations
The decline of a significant proportion of waterbuck populations probably reflects the species' susceptibility to poaching, since it occurs mainly along watercourses where poaching activities are often concentrated. If current trends continue, both subspecies but particularly the defassa will disappear from substantial areas where they still occur and hence the distribution of the surviving populations will become more fragmented. However, the species' overall status may not chance as long as significant parts of its range continue to receive adequate protection and its numbers continue to increase on private land.

Other relevant subspecies
K. e. ellipsiprymnus

Description
Total length: 2.10 - 2.74 m
Tail length: 35 cm

Trend:
About 60 % of the subspecies live in protected areas. Important populations of the Defassa Waterbuck persist in areas such as the Awash Valley and Omo-Mago-Murule in Ethiopia.

Ellipsen waterbuck

Kobus ellipsiprymnus ellipsiprymnus (Ogilby, 1833)
F:
German: Ellipsen-Wasserbock

Other relevant subspecies
K. e. defassa

Description
Total length: 2.10 - 2.74 m
Tail length: 35 cm
Shoulder height: 1.30 m
Weight: 250 - 270 kg
Gestation: 8 months

Conservation Status

IUCN Red List Category, ver 3.1:

- http://www.iucnredlist.org/apps/redlist/details/11039/0

Trend:
More than half of Ellipsen waterbuck live in protected areas (plus 13% on private land). Important populations of the Ellipsen waterbuck occur in areas outside this region. The Ellipsen waterbuck is probably extinct in Ethiopia.
