Female oribi in the northern Serengeti
Oribi (Ourebia ourebi) is a small antelope found in eastern, southern and western Africa. The sole member of its genus, the oribi was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1782. Eight subspecies are identified. The oribi reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). This antelope features a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. Only males possess horns; the thin, straight horns, 8–18 centimetres (– in) long, are smooth at the tips and ringed at the base. The oribi is active mainly during the day. The oribi occurs in a variety of habitats – from savannahs, floodplains and tropical grasslands with 10–100 centimetres (– in) tall grasses to montane grasslands at low altitudes, up to 2,000 metres (6,600 ft) above the sea level. Recently burnt areas often attract groups of oribi. The choice of habitat depends on the availability of cover needed to escape the eyes of predators. Population densities typically vary between 2 and 10 individuals per km2; however, densities as high as 45 individuals per km2 have been recorded in tropical grasslands that receive over 110 centimetres (43 in) of annual rainfall and open floodplains. The oribi's range overlaps with those of larger grazers such as the African buffalo, hippopotamus, hartebeest, Thomson's gazelle and topi. These separate species often occur in close proximity to each other, increasing predator vigilance. This antelope is highly sporadic in distribution; it occurs mainly in eastern, southern and western Africa, ranging from Nigeria and Senegal in the west to Ethiopia and Eritrea in the east and southward to Angola and the Eastern Cape (South Africa).
