De Brazza’s monkeys are arboreal, meaning they live in trees, but they are also active on land and have been observed swimming. They live in closed canopy forests with dense vegetation, and near rivers. The environments are humid, and may have swamps and seasonal flooding.
De Brazza’s monkeys are sexually dimorphic, meaning that sexual roles are distinct and males are socially dominant. They are polygynous (males have multiple female partners); however, there have been some reports of monogamy. Females remain in their mother’s group for life, while males leave the group when they reach sexual maturity. At this point, males often compete for access to a group of females. Breeding season generally occurs during February and March, or whenever food is available. Females usually give birth to one infant, though twins are rare. Gestation period is 5-6 months and the average birth weight is about 9 ounces. Time to weaning is 12 months and age at sexual maturity is 5-6 years.
De Brazza monkeys are omnivores; however, fruits form the most important part of their diet. They also eat flowers, leaves, mushrooms, beetles, termites, worms, and lizards. While foraging, the monkeys store food in their cheek pouches and then eat it later when they are in a safer area.
The De Brazza’s monkey is an Old World monkey endemic to the wetlands of central Africa. It is one of the most widespread African primates that live in forests.
