The olive colobus monkey (Procolobus verus), also known as the green colobus or Van Beneden's colobus, is a species of primate in the family Cercopithecidae. Its English name refers to its dull olive upperparts.[3] It is the smallest example of all colobine monkeys and is rarely observed in its natural habitat because of its cryptic coloration and secretive nature.[4] It is found in the rain forests of West Africa, ranging from southern Sierra Leone to Nigeria.[2] The IUCN Red List classifies the olive colobus as vulnerable[2] (previously near threatened), with the cause of its decline attributed to habitat loss and hunting.[2] Though much of the land within the range of the olive colobus has been affected by human activities, it retains its ability to thrive in small degraded forest fragments.[2]
