The Uzungwa red colobus (Piliocolobus gordonorum), also known as the Udzungwa red colobusor Iringa red colobus, is a species of primate in the family Cercopithecidae. It is endemic to riverine and montane forest in the Udzungwa Mountains in Tanzania. It is threatened by habitat loss.
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae. Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons, macaques, and mabahlls. Common names for other Old World monkeys include the talapoin, guenon, colobus, douc, vervet, gelada, mangabey, langur, mandrill, surili (Presbytis), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 55 million years ago.
The Zanzibar red colobus is a species of red colobus monkey endemic to Unguja, the main island of the Zanzibar Archipelago, off the coast of Tanzania. It is also known as Kirk's red colobus after Sir John Kirk, the British Resident of Zanzibar who first brought it to the attention of zoological science. It is now classified as an endangered species and in the mid-1990s was adopted as the flagship species for conservation in Zanzibar. The population is still decreasing, and conservationists are attempting to work with the local government to devise a proper, effective strategy to protect the population and habitat. Challenges include the species' habitat, which is limited to the archipelago. The species has been reclassified three times; it was previously in the genus Colobus, then in the genus Procolobus, and later in the genus Piliocolobus.
Red colobuses are Old World monkeys of the genus Piliocolobus. It was formerly considered a subgenus within the genus Procolobus, which is now restricted to the olive colobus. They are closely related to the black-and-white colobus monkeys, and some species are often found in groups with the blue monkey. The western red colobus is frequently hunted by the common chimpanzee.
Miss Waldron's red colobus is a species of the red colobus native to West Africa. It had previously been described as a subspecies of the western red colobus, P. badius. It has not been officially sighted since 1978 and was considered extinct in 2000. However, new evidence suggests that a very small number of these monkeys may be living in the southeast corner of Côte d'Ivoire. The IUCN Red List notes Miss Waldron's red colobus as critically endangered.
The western red colobus, 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. It is often hunted by the common chimpanzee. In 1994, western red colobus monkeys infected many chimpanzees with Ebola virus when the chimpanzees hunted the monkeys as prey.
Jackson's mongoose is a mongoose species native to montane forests in Kenya, Uganda and Tanzania. It appears to be rare and has been classified as Near Threatened since 2008.
Procolobus is the genus of the olive colobus. It formerly included the red colobus monkeys now included in the genus Piliocolobus. They are mainly folivorous and most of the species are threatened.
Pennant's colobus or Pennant's red colobus is a species of tree-dwelling primate in the family Cercopithecidae. It is endemic to tropical Central Africa. Three subspecies have traditionally been recognised but its distribution is peculiarly disjunct and has been considered a biogeographical puzzle. with one population on the island of Bioko, a second in the Niger River Delta in southern Nigeria, and a third in east-central Republic of Congo. It is found in rainforests and marshy forests. It is threatened by habitat loss and hunting for bushmeat. One subspecies, bouvieri, is rated as critically endangered; although it was last photographically documented in 2015, it may be on the brink of extinction.
The Tana River red colobus, also called the eastern red colobus, is a highly endangered species of primate in the family Cercopithecidae. It is endemic to a narrow zone of gallery forest near the Tana River in southeastern Kenya.
The olive colobus monkey, 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. 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. It is found in the rain forests of West Africa, ranging from southern Sierra Leone to Nigeria. As of 2019, the IUCN Red List classifies the olive colobus as vulnerable, with the cause of its decline attributed to habitat loss and hunting. 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.
Preuss's red colobus is a red colobus primate species endemic to the Cross-Sanaga Rivers ecoregion. An important population occurs in Korup National Park, Southwest Province, Cameroon, but the species' distribution is localized. The species is considered present in adjacent Cross River National Park - Oban Division in Nigeria and hunter reports suggest that few groups remain in Nkwende Hills and Nta Ali Forest Reserve in the broader Korup region. A population is also present in Ebo forest, Littoral Province of Cameroon.
Central African red colobus is the traditional name for several species of red colobus monkey that had formerly been considered a single species, Piliocolobus foai. Central African red colobus monkeys are found in humid forests in the Democratic Republic of the Congo, the Republic of the Congo, the Central African Republic and South Sudan.
Thollon's red colobus, also known as the Tshuapa red colobus, is a species of red colobus monkey from the Democratic Republic of the Congo and lower Republic of the Congo. It is found south of Congo River and west of Lomami River. It had once been considered a subspecies of the P. badius. It was recognised as a distinct species by Dandelot in 1974, and this was followed by Groves in 2001, while others have suggested it should be considered a subspecies of P. rufomitratus.
The Ugandan red colobus or ashy red colobus is an endangered species of red colobus monkey, recognised as a distinct species since 2001. There is disagreement however over taxonomy with many considering the Ugandan red colobus to be a subspecies. The Ugandan red colobus is an Old World monkey which is found in 5 different locations across Uganda and Tanzania.
The Niger Delta red colobus is a critically endangered species of colobus monkey endemic to the western part of the Niger Delta. It is threatened by hunting and habitat loss.
Bouvier's red colobus is a species of colobus monkey rediscovered in the Republic of the Congo in 2015, after four decades without a confirmed sighting.
Temminck's red colobus is a type of red colobus monkey from the Gambia, Casamance, Guinea-Bissau and northwestern Guinea. It has historically been regarded as a subspecies of the western red colobus, and the Integrated Taxonomic Information System maintains this classification, but many recent taxonomies classify it as a separate species.
Foa's red colobus or the Central African red colobus, is a species of red colobus monkey found in the Democratic Republic of the Congo.
Oustalet's red colobus is a species of red colobus monkey. It lives in various types of forest in southern South Sudan, southern Central African Republic, northern Democratic Republic of the Congo and northeastern Republic of the Congo. It eats leaves, fruit, flowers, buds and possibly seeds. Males have a head and body length of between 45.9 and 68 cm with a tail length of between 55.5 and 73 cm. Females have a head and body length of between 52 and 64 cm with a tail length of between 68 and 73 cm. Males weigh about 12.5 kg (28 lb) and females weigh about 8.2 kg (18 lb).
