The oribi (Ourebia ourebi) is a small antelope found in eastern, southern and western Africa. The sole member of its genus, it was described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1783. While this is the only member in the genus Ourebia, 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). It possesses 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 (3.1–7.1 in) long, are smooth at the tips and ringed at the base.
Typically diurnal, the oribi is active mainly during the day. Small herds of up to four members are common; males defend their group's territory, 25–100 hectares (62–247 acres) large. It is primarily a grazer, and prefers fresh grasses but also browses occasionally. A seasonal breeder, the time when mating occurs varies geographically. Unlike all other small antelopes, oribi can exhibit three types of mating systems, depending on the habitat – polyandry, polygyny and polygynandry. Gestation lasts for six to seven months, following which a single calf is born; births peak from November to December in southern Africa. Weaning takes place at four to five months.
The oribi occurs in a variety of habitats – from savannahs, floodplains and tropical grasslands with 10–100 centimetres (3.9–39.4 in) tall grasses to montane grasslands at low altitudes, up to 2,000 metres (6,600 ft) above the sea level. This antelope is highly sporadic in distribution, ranging from Senegal in the west to Ethiopia and Eritrea in the east and southward to Angola and the Eastern Cape (South Africa). The oribi has been classified as Least Concern by the IUCN; numbers have declined due to agricultural expansion and competition from livestock. Wikipedia →

Likely
About 40% of wildlife watchers report an Oribi sighting in Niokolo-Koba National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 15 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report an Oribi in Niokolo-Koba National Park on a given day, against about 10% in April–June and November–December, the lowest months. That is one of Niokolo-Koba National Park's driest months, with almost no rain against 300 mm in August. July to October have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Oribi sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 7
Of the 7 parks where we can rate Oribi sightings, Niokolo-Koba National Park ranks 4th at about 40%. The best odds are in Murchison Falls National Park (Uganda, about 70%), Kidepo Valley National Park (Uganda, about 70%) and Akagera National Park (Rwanda, about 40%). All parks ranked.
Same family: Bovidae
The closest relatives of the Oribi that you can see in Niokolo-Koba National Park (family Bovidae, Bovids) are Northern Bushbuck (about 70%), Waterbuck (about 70%) and Kob (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oribi is recorded against all the mammals logged in Niokolo-Koba National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
