Oribi (Ourebia ourebi) lives in open savanna across Sub-Saharan Africa. It feeds on grasses and leaves. Its conservation status is Least Concern.
Fascinating facts about the Oribi
- Oribi are the only small antelope that can shift among polyandry, polygyny and polygynandry according to the habitat they occupy. They are typically diurnal and usually form small herds of up to four individuals, while males guard territories that span 25-100 hectares. Research shows that in areas with high predator risk, polygyny becomes dominant because it encourages group formation as an anti-predator strategy.
- Male oribi grow thin, straight horns that are usually 8-18 centimetres long, smooth at the tips and ringed at the base. In 1998 a specimen from Malawi displayed an exceptional horn length of 19.1 centimetres, the longest recorded for the species. Because only males bear horns, this measurement highlights the upper limit of their natural variation. The typical horn size therefore remains well below this record, underscoring the rarity of such individuals.
- The oribi is listed as Least Concern by the IUCN, with a total population estimated at 750,000 individuals in 2008. However, in Côte d'Ivoire's Comoé National Park the species suffered a dramatic 92 % decline, a drop directly linked to intense poaching pressure. This sharp reduction stands in contrast to the overall stable status of the species, illustrating how localized threats can severely impact regional numbers despite a favourable global assessment.
- While typical densities are 2-10 animals per km², surveys have found up to 45 oribi per km² in tropical grasslands receiving over 110 cm of rain annually. Groups of oribi congregate in the rainy season, when grasses are abundant.
- Oribi groups perform a "dung ceremony", gathering temporary dung middens that all members use. The intensity of marking increases with the number of male neighbours.

About the Oribi
In the sun-drenched grasslands, the oribi, a diminutive antelope with large, watchful eyes, dances across the savannah with an air of quiet elegance, its slender legs moving with a swift, economic precision that belies its ability to reach remarkable speeds when threatened. As it grazes, its large ears twitch and rotate, ever-vigilant for the telltale signs of predators lurking in the underbrush, a constant reminder of the delicate balance of power in this unforgiving yet beautiful landscape. With its tawny coat blending seamlessly into the rustling grasses, the oribi embodies the very essence of adaptability and resilience.
