Collared Mangabey, Cercocebus torquatus

The collared mangabey (Cercocebus torquatus) is a species of primate in the Old World monkey family. Its other common names include the red-capped mangabey and the white-collared mangabey, which allows for some confusion with the sooty mangabey. The collared mangabey is native to Africa, with a range including western Nigeria extending into south and east Cameroon. It can also be found through Equatorial Guinea and from Gabon to the Gabon-Congo border near the Atlantic shore.

The collared mangabey varies in size depending on sex, with males reaching a body length of up to 26 inches and females reaching up to 24 inches. Males can weigh an average of 22 pounds, while females are slightly smaller reaching 19 pounds at most. They are grey in color, with white fur occurring around the neck, and a red crown on top of the head. The ears are black, and the eyelids bear a striking white color, causing some to call it the “four-eyed monkey”. The tail is dark grey in color and is often longer than the body, and held in an upright position.

Groups of the collared mangabey can number between 10 to 35 individuals. Vocalizations include barks and cackles, which are produced in order to keep track of each member of the group. There is not a known mating season for these monkeys, although they are able to mate at five to seven years of age. Their diet consists mainly of seeds and fruit, but they will also eat flowers, leaves, foliage, mushrooms, gums, and even invertebrates.

The collared mangabey is threatened by habitat loss and bushmeat hunting. Because of this and its small range, it has been given a conservation status of “Vulnerable” on the IUCN Red List and appears on Appendix II of CITES as well as on Class B of the African Convention on the Conservation of Nature and Natural Resources.
