A red-capped mangabey has a red cap, a white collar, and white eyelids. The back is dark brown to black, and the dark tail has a white tip. The tail is usually held over the body with the tip just over the head. The underparts are white.
Longevity
Red-capped mangabeys in zoos can live into their 40's, although a typical lifespan is somewhat shorter. Wild red-capped mangabeys can live up to 30 years.
Behavior
Red-capped mangabeys are more willing to leave the trees compared to some other mangabey species. They have been observed traveling on the ground in single-file and feeding off the forest floor. When in the trees, they prefer the lower-level branches of the understory. Red-capped mangabeys live in multi-male and multi-female groups of 14 to 60 individuals. They do not form all-male groups, but solitary males have been observed. They are diurnal and relatively peaceful; they range over large territories, but they do not usually exert themselves to dispel other groups from their territory. Males give a very loud, two-note barking call that both calls the group to him, and alerts other groups to stay away. This vocalization thus plays a role in regulating group spacing and minimizing inter-group aggression.
Reproduction
Red-capped mangabeys rearch sexual maturity at 5-7 years of age. They have a gestation period of 170 days, and typically give birth to one young every year and a half. There is no breeding season, although most births tend to occur from March to August.
Conservation Status
On the 2011 IUCN Red List of Threatened Species, the red-capped mangabey is listed as Vulnerable.
