waldronae by the Bandama River in Ivory Coast. It is unclear exactly where the ranges of P. Its range includes various fragmentary populations in Sierra Leone, and contiguous populations in Liberia, Guinea and western Ivory Coast. The red colobus is endemic to tropical West Africa. Compared to monkeys in the genus Colobus, the nostrils are V-shaped, the digits are long and the big toe short. It does not have long fringes of hair, or tufts of hair on the tail. It has red or chestnut-brown head and limbs and black, slatey-grey or dark brown upper parts. 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). Groves concurs with this revision, although not all primatologists agree. Under more recent taxonomies, these are generally considered separate species. waldronae is critically endangered, possibly even extinct. Miss Waldron's red colobus, Piliocolobus badius waldronae.Temminck's red colobus, Piliocolobus badius temminckii.Bay red colobus, Piliocolobus badius badius.Subspecies Īccording to Groves (2005) the Western red colobus has three subspecies, including the nominate: In 1994, western red colobus monkeys infected many chimpanzees with Ebola virus when the chimpanzees hunted the monkeys as prey. It is often hunted by the common chimpanzee. All other species of red colobuses have formerly been considered subspecies of P. 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.

" Impending Extinction Crisis of the World's Primates: Why Primates Matter." Science Advances, vol. Here's the list of the 25 most endangered primates on the planet, according to the IUCN Primates in Peril report.Įstrada, Alejandro, et al. That's according to the latest list of Earth's 25 most endangered primates, which is updated every two years by scientists from the International Union for the Conservation of Nature (IUCN), the Bristol Zoological Society (BZS), the International Primatological Society (IPS), and Conservation International (CI). Our closest living relatives are being wiped out by large-scale habitat destruction - especially from the burning and clearing of tropical forests, hunting for food, and the illegal wildlife trade. More than half of those primates are now in grave danger of becoming extinct, warns a report by the world's top primatologists and conservationists.
But behind this conspicuous sea of people, the story of Earth's roughly 700 other primate species and subspecies is a lot less triumphant. Earth is a primate planet, thanks mainly to the estimated 7.5 billion humans who inhabit and reshape its surface.
