What do they eat?

White-naped mangabeys are omnivores, meaning they feed on both plants and animals. They have a diverse diet that includes seeds, fruit, nuts, fungi and invertebrates. They mainly forage for food on the forest floor, but also spend time foraging in trees. They have strong jaws and large incisor teeth that allow them to eat hard nuts and fruit.

Troop

Closest related species / sister species

The white-naped mangabey was until recently considered a subspecies of the grey mangabey. Following a reclassification, it is now considered a separate species. Its closest related species is the sooty mangabey.

Fun Facts!

Communication

Mangabeys communicate using shrieks, whoops and grunts, as well as by blinking their white eyelids and using other facial gestures.

Storing food

White-naped mangabeys have large cheek pouches that they use to store food in.

Stone comb

Some species of mangabey have been observed grooming their infants using a stone.

Family life

White-naped mangabeys are social animals. They live in troops of 10-90 individuals, this number usually depends on the availability of food and shelter. Each troop contains a number of males and females. There is usually one adult male per troop that acts as the leader and protector. However, in larger groups, there can be two to three dominant males that will forage for food with their own family unit. The females stay with their troops from birth. Males will leave the troop when they are 5 years old in search of another troop to join.

What is Dublin Zoo doing?

In 2001 Dublin Zoo was one of 11 European zoos, together with two nature conservation organisations, that established the West African Primate Conservation Action (WAPCA). The aim of WAPCA is the conservation of endangered primate species in western Africa, including the white-crowned mangabey. Dublin Zoo also participates in the EEP breeding programme for this species.
