De Brazza´s guenon or De Brazza´s monkey, is a species of catarrhine primate from the family Cercopithecidae.

General characteristics

You can easily tell whether a De Brazza´s Guenon is male or female. There is quite a big difference in size between the two. Females measure about 40cm and weigh 4.5kg while males measure up to 60cm and weigh around 7kg, almost twice more. 

Their fur is usually dark gray except on the back, which is reddish brown, and on the limbs and tail, which are black. On the face, they have a reddish forehead and a long white beard that gives them the characteristic “bishop” appearance.  

Both sexes have dilatable cheek pouches that they use to carry food while foraging.


Their diet consists mainly of fruit, leaves and tender shoots, although from time to time they also eat insects and small vertebrates.


This type of monkeys are quiet animals. They have a lifespan of 25 years and spend most of their time in the branches of trees, where they can remain still for up to 5 hours.

They are grouped in families led by the male who may have one or more females. They communicate with booming sounds. They are usually heard early in the morning when the male calls out to establish his territory, although he will also use this call to rejoin the group if they become separated.


Females reach sexual maturity at about 5 years of age, while males do not reach maturity until about 6 years of age.

Their gestation period lasts between 5 and 6 months and only one calf is born at each birth, which is cared for exclusively by the mother.


De Brazza´s Guenon have still a stable population, but agricultural needs and living space requirements for a growing human population have resulted in fragmentation of their habitat. 


They are from central Africa and they usually live in tropical rainforests and in wet and swampy areas.
