About the Western Red Colobus

The western red colobus (Piliocolobus badius), also known as the bay red colobus, rust red colobus or Upper Guinea red colobus, is a species of Old World monkey in West African forests from Senegal to Ghana. All other species of red colobuses have formerly been considered subspecies of P. badius.

The monkey is a frequent prey of the common chimpanzee. In 1994, western red colobus monkeys infected many chimpanzees with Ebola virus after being hunted and consumed by the chimps. The western red colobus has two subspecies, including the nominate: Bay red colobus, Piliocolobus badius badius

Temminck's red colobus, Piliocolobus badius temminckii Both subspecies are endangered. The western red colobus grows to a head-and-body length of 450 to 670 mm (18 to 26 in) with a tail of 520 to 800 mm (20 to 31 in), and a weight of between 5 and 11 kg (11 and 24 lb). It has red or chestnut-brown head and limbs and black, slatey-grey or dark brown upper parts. It does not have long fringes of hair, or tufts of hair on the tail. Compared to monkeys in the genus Colobus, the nostrils are V-shaped, the digits are long and the big toe is short. Wikipedia →
