Bongo (Tragelaphus eurycerus)

The bongo is a herbivorous, mostly nocturnal forest ungulate; it is among the largest of the African forest antelope species. There are two sub-species, the western bongo and the eastern bongo. Bongos are found in tropical jungles with dense undergrowth up to an altitude of 4,000 meters (12,800 ft) in Central Africa, with isolated populations in Kenya, and several West African countries. Like other forest ungulates, bongos are seldom seen in large groups. Males, called bulls, tend to be solitary, while females with young live in groups of six to eight. They feed on tree/bush leaves, bushes, vines, bark and pith of rotting trees, grasses/herbs, roots, cereals, shrubs, and fruits. The IUCN Antelope Specialist Group considers the western or lowland bongo, T. e. eurycerus, to be Lower Risk (Near Threatened), and the eastern or mountain bongo, T. e. isaaci, of Kenya, to be Critically Endangered!
