Cercopithecus

Cercopithecus is a genus of Old World monkeys in the subfamily Cercopithecinae, commonly referred to as guenons. The genus comprises numerous species native to sub-Saharan Africa, occupying a range of habitats from tropical forests to woodlands and riverine systems. Members are generally small to medium-sized arboreal primates, with facial markings and pelage that vary widely among species.

They are omnivorous, feeding on fruit, seeds, leaves, blossoms, and invertebrates. Like other cercopithecines, they possess cheek pouches used to store food while foraging, and they rely on agile climbing and leaping through trees. Social groups are typically multi-male and multi-female, with grooming and vocal communications forming important social bonds. Species exhibit a range of color patterns and territorial displays that aid in species recognition and group defense.

Notable species include the red-tailed guenon (Cercopithecus ascanius) and the Diana monkey (Cercopithecus diana).

Many Cercopithecus species are threatened by habitat loss, fragmentation, and hunting, with conservation statuses ranging from near threatened to endangered. Research on their ecology and behavior provides insight into primate social systems and forest ecosystem dynamics.
