The Grey-cheeked Mangabey is a dark monkey, looking in shape overall like a small, hairy baboon. Its thick brown fur is almost black in its forest home, with a slightly rufus or golden mane around the neck. The sexes are similar, with the males slightly larger than the females.
The Grey-cheeked Mangabey lives in a variety of habitats within the forests of Central Africa, it is generally thought to live in either swamp or primary forests, in some areas it has also been found in secondary forest as well. These species have been considered to be restricted to the forest canopy, however more recently habituated troops have been observed on the forest floor.
They feed primarily on fruit, particularly figs of the genus Ficus, taking other fruits seasonally, as well as shoots, flowers and insects.
The Grey-cheeked Mangabey lives in groups of between 5 to 30 individuals. The groups have either a single male without a single dominant male. Young males leave the troop once they are adult and join other troops, whereas the females stay in the troop of their birth.
If troops become too large they may split. Confrontations between troops are rare, as this mangabey will usually avoid other troops. Their territories cover several square miles of forest, and can both overlap with other troops and shift over time. The grey cheeked mangabey ranges in Uganda’s forests like kibale national park and semuliki national park.
