The bongo (Tragelaphus eurycerus) is a large, mostly nocturnal, forest-dwelling antelope, native to sub-Saharan Africa. Bongos are characterised by a striking reddish-brown coat, black-and-white markings, white-yellow stripes, and long, slightly spiraled horns. Bongos have complex social interactions and are found in African dense forest mosaics. They are the third-largest antelope in the world.
In 2000, the Association of Zoos and Aquariums in the US upgraded the bongo to a Species Survival Plan participant and in 2006 added the Bongo Restoration to Mount Kenya Project to its list of the Top Ten Wildlife Conservation Success Stories of the year. As of 2013, these successes have been compromised by reports of possibly only 100 mountain bongos left in the wild due to logging and poaching.
The scientific name of the bongo is Tragelaphus eurycerus, and it belongs to the family Bovidae. It was first described by Irish naturalist William Ogilby in 1837. The generic name Tragelaphus is composed of two Greek words: trag-, meaning a goat; and elaphos, meaning deer. The specific name eurycerus originated from the fusion of eurus (broad, widespread) and keras (an animal's horn... Wikipedia →

Possible
About 30% of wildlife watchers report a Bongo sighting in Odzala-Kokoua National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 32 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
November and December
In those months about 40% of wildlife watchers report a Bongo in Odzala-Kokoua National Park on a given day, against under 5% in February–May and July, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Bongo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Odzala-Kokoua National Park, in our data
Odzala-Kokoua National Park is the only park on Wallace's Line with enough records to rate Bongo sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Tragelaphus
The closest relatives of the Bongo that you can see in Odzala-Kokoua National Park (genus Tragelaphus, Spiral-horned Antelopes) are Northern Bushbuck (about 40%) and Sitatunga (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bongo is recorded against all the mammals logged in Odzala-Kokoua National Park (10 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.
