collared mangabey

The Collared Mangabey, known scientifically as <em>Cercocebus torquatus</em>, is an Old World monkey belonging to the family Cercopithecidae. As a member of the genus Cercocebus, <em>Cercocebus torquatus</em> is recognised by its distinctive appearance, which typically includes a pale or white collar of fur around the neck region that contrasts with darker body colouration, lending the species its common name. Collared Mangabeys are typically associated with tropical rainforest habitats, particularly swamp forests and riverine forest environments, where they forage for fruits, seeds, invertebrates, and other food items on both the ground and in the canopy. The species is known for its loud, distinctive calls, which are used for communication across forest territories. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Mangabey is currently assessed as Endangered on the IUCN Red List, primarily due to ongoing habitat loss from forest clearance and hunting pressure across its range.
