Habi­tat

Col­lared mangabeys are ar­bo­real as well as ter­res­trial, but they mainly in­habit lower lev­els of the forests, es­pe­cially in swamp forests. Their flex­i­bil­ity on the ground and among the trees al­lows them to have a rather broad range of habi­tat, in­clud­ing swamp and agri­cul­tural areas. Col­lared mangabeys typ­i­cally use the trees to ob­tain foods and as a haven for hid­ing and sleep­ing, but they usu­ally es­cape en­e­mies and preda­tors (leop­ards and ea­gles) ter­res­tri­ally (on the ground).

Re­pro­duc­tion

Most col­lared mangabey reach sex­ual ma­tu­rity at age 5-7 years. The ges­ta­tion pe­riod lasts for about 170 days, and a fe­male gives birth to only a sin­gle young each time. The av­er­age weight of each young is un­known. It seems that col­lared mangabeys lack a well-de­fined breed­ing pe­riod; how­ever, most of our in­for­ma­tion de­rives from species liv­ing in cap­tiv­ity and lit­tle is known about their re­pro­duc­tion in the wild.

Be­hav­ior

Col­lared mangabeys are found in so­cial groups con­tain­ing 10-35 in­di­vid­u­als. These groups con­tain sev­eral males, and most of them co­ex­ist peace­fully and rarely dis­play any type of dom­i­nance be­hav­ior. Each mem­ber within a group ex­hibits very ex­pres­sive be­hav­ior. It walks with its tail arched over its back, with the white tip held just above its head. The tail move­ment and the tap­ping of its head may pro­vide so­cial cues or serve as a form of com­mu­ni­ca­tion with other mem­bers of the group. In ad­di­tion, many col­lared mangabeys dis­play by con­tin­u­ously lift­ing and low­er­ing their con­spic­u­ous white eye­lids.

Food Habits

Sim­i­lar to other species of Cer­co­ce­bus, col­lared mangabeys feed on fruits, nuts, seeds, young leaves, grass, mush­rooms, and in­ver­te­brates.

Eco­nomic Im­por­tance for Hu­mans: Neg­a­tive

Many na­tives al­lege the col­lar mangabeys raid plan­ta­tions, caus­ing se­vere dam­age to crops.
