Oribi

Ourebia ourebi (Zimmermann, 1783)
French: L' Ourébie
German: Oribi; Bleichböckchen
Swahili: Taya

Endemic subspecies
O. ourebi montana
O. ourebi haggardi

Description
Total length: 92 - 140 cm
Tail length: 6 - 15 cm
Shoulder height: 50 - 67 cm
Weight: 12 - 22 kg
Gestation: ~ 7 months

The Oribi is a tall slender antelope of medium-small size and sandy body colour (yellowish or reddish tinted), with white undersides, upper throat, mouth and ear linings.
The light-coloured muzzle deflects down sharply from the forehead (unlike the black-bridged retroussé nose of the Steinbuck (Raphicerus cempestris), nor are the eyes rimmed by intensely black lids as in the Steinbuck). The ears are of moderate size, in addition to hoof (pedal) and groin (inguinal) glands, the oribi has sent brushes the knees and ankles and black gland patches below the ears. The face glands (preorbital) are also exceptionally well developed. Alert and shy, the Oribi's piercing whistle is frequently heard as it flees from the observer with a characteristic rocking-horse gait.

Distribution
O. o. montana: Sudan, Ethiopia
O. o. haggardi: E, S Somalia

Ecology
Its habitat is grassland maintained by fire or heavy grazing. They prefer flats or gentle slopes and are commonest on open lawns of grass kept short by compaction, termites, poor soils, fast drainage, trampling or heavy grazing by large herbivores. Such herd not only improve the oribi's range, but may also buffer them from predation. Oribis tend to decline wherever such herds have been severely reduced or exterminated. On extensive floodplains oribis favour the less waterlogged areas where termitaries, herbs and woody growth provide cover and supplement the diet. Their mating system in East Africa is polygyny.

Conservation Status

IUCN Red List Category, ver 3.1:

- http://www.iucnredlist.org/apps/redlist/details/15730/0

Trend:
Declining, but there is no current data available for many regions. Its distribution and abundance are increasingly centred on protected areas (about half the total population occurs in and around protected areas) and some other areas where human population densities are very low

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

Recommendations
None.

Oribi

Ouribia ouribi montana (Cretzschmar, 1826)

G:

Endemic subspecies
O. ouribi haggardi

Description
Total length: 92 - 140 cm
Tail length: 6 - 15 cm
Shoulder height: 50 - 67 cm
Weight: 12 - 22 kg
Gestation: ~ 7 months

Conservation Status

IUCN Red List Category, ver 3.1.:

- http://www.iucnredlist.org/apps/redlist/details/15730/0

Trend: ?
It survives in viable numbers in areas such as Dinder and Radom N.P.in Sudan. It probably still occurs widely at low moderate densities in southern Sudan. In Ethiopia it survives quite widely in open habitats within its historical range, including some settled areas. It occurs in low to moderate numbers in areas such as Senkelle Wildlife Sanctuary, Mago and gambella National Parks and Omo West, Maze and Akobo Controlled Hunting Areas. It is common in Omo N.P. where it occurs throughout the park's northern grassland and on hills in the south.

Recommendations
None.
