It ranges across the swamps, bamboo and dry mountain forests of Angola, Cameroon, Central African Republic, Congo, The Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Kenya, Sudan, and Uganda.
De Brazza’s Monkey has grey agouti fur with a reddish brown back, black limbs and tail and a white rump. A white stripe runs down its thigh and an orange crescent-shaped marking appears on its forehead. Its white eyelids match its muzzle and beard. Both male and female De Brazza’s Monkeys have cheek pouches in which they carry food while they forage and males have a blue scrotum.
Hamlyn’s Monkey (Cercopithecus hamlyni), also known as the Owl-faced Monkey, is a species of Old World monkey that inhabits the bamboo and primary rainforests of the Congo. Hamlyn’s Monkey is exceedingly rare and little is known about it.
However what is known is that it tends to be widely dispersed throughout the eastern part of Congo where it corresponds quite closely to another species of monkey, L’Hoest’s Monkey (C. lhoesti).
Hamlyn’s monkey travels terrestrially and is thought that it may be nocturnal. The male is much larger than the female, with the average adult weighing 7 to 10 kilograms, while females weigh on average 4.5 to 6 kilograms. It is thought to be a frugivore-folivore in diet.
