De Brazza’s monkeys live along rivers in forest habitats in Central Africa, from Cameroon to Ethiopia, and Kenya to Angola. They are primarily herbivores.
This monkey is named for Pierre Savorgnan de Brazza, an Italian explorer originally named Pietro Savorgnan di Brazza. He lived from 1852 to 1905 and founded a city that is named for him: Brazzaville, the capital of the Republic of the Congo.
De Brazza’s monkey behavior and facts

- They are arboreal, dwelling in the tree canopy, and prefer dense vegetation near rivers. They live in lowland and submontane tropical moist forest, swamp forest, semi-deciduous forest and Acacia forest.

De Brazza’s monkeys, the Oregon Zoo and you
These monkeys live in the Africa Savanna exhibit, where they eat monkey chow, fruit and vegetables. They are common and widespread across their range, though hunting and habitat loss have caused declines in parts of their traditional habitat.
