Colobus angolensis ruwenzorii [1] Thomas, 1901 |
The Ruwenzori colobus (Colobus angolensis ruwenzorii), also known as Ruwenzori black-and-white colobus, is a subspecies of the Angola colobus. [1] This primate is distributed from the Afromontane forests of the Ruwenzori Mountains across the mountains in Burundi and Rwanda to the northern shore of Lake Tanganyika. [2]
In 1901, Oldfield Thomas described two skins of Ruwenzori colobus zoological specimens that were collected at the northwestern slopes of the Ruwenzori Mountains in Bwamba Country of western Uganda. Thomas considered it a species using the scientific name Colobus ruwenzorii. [3]
The Ruwenzori colobus is black with hair on the shoulders between 23 and 33 cm (9.1 and 13.0 in) long. Its tail is also black and greyish-white at the end. It has white bushy tufts on the cheeks. [3] The white hair on the forehead forms a crest. [2]
The Ruwenzori colobus occurs at Lake Nabugabo and Rwenzori Mountains National Park in Uganda. [4] Troops of 300 to 400 individuals inhabit Rwanda's Nyungwe National Park. [5]
Some authors reports indicate that it perhaps also occurs in some Tanzanian regions. [6]
The Ruwenzori colobus is a highly arboreal and acrobatic leaf-eater. Its diet consists of about two thirds of leaves and one third of fruit and seeds. [7]
Although all Colobus species are very sociable, they usually move on the troops of several hundred animals. [7]
Black-and-white colobuses are Old World monkeys of the genus Colobus, native to Africa. They are closely related to the red colobus monkeys of genus Piliocolobus. There are five species of this monkey, and at least eight subspecies. They are generally found in high-density forests where they forage on leaves, flowers and fruit. Social groups of colobus are diverse, varying from group to group. Resident-egalitarian and allomothering relationships have been observed among the female population. Complex behaviours have also been observed in this species, including greeting rituals and varying group sleeping patterns. Colobi play a significant role in seed dispersal.
The mantled guereza, also known simply as the guereza, the eastern black-and-white colobus, or the Abyssinian black-and-white colobus, is a black-and-white colobus, a type of Old World monkey. It is native to much of west central and east Africa, including Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda and Chad. The species consists of several subspecies that differ in appearance. It has a distinctive appearance, which is alluded to in its name; the long white fringes of hair that run along each side of its black trunk are known as a mantle. Its face is framed with white hair and it has a large white tail tuft.
The Nyungwe Forest is located in southwestern Rwanda, on the border with Burundi, where it is contiguous with the Kibira National Park to the south, and Lake Kivu and the Democratic Republic of the Congo to the west. The Nyungwe rainforest is probably the best preserved montane rainforest in Africa. It is located in the watershed between the basin of the Congo River to the west and the basin of the river Nile to the east. From the east side of the Nyungwe forest comes also one of the branches of the Nile sources.
Rwenzori Mountains National Park is a Ugandan national park and UNESCO World Heritage Site located in the Rwenzori Mountains. Almost 1,000 km2 (386 sq mi) in size, the park has Africa's third highest mountain peak and many waterfalls, lakes, and glaciers. The park is known for its beautiful plant life.
Mgahinga Gorilla National Park is a national park in southwestern Uganda. It was created in 1991 and covers an area of 33.9 km2 (13.1 sq mi).
The Albertine Rift montane forests is a tropical moist broadleaf forest ecoregion in east-central Africa. The ecoregion covers the mountains of the northern Albertine Rift, and is home to distinct Afromontane forests with high biodiversity.
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. 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 Angola colobus, Angolan black-and-white colobus, or Angolan colobus is a primate species of Old World monkey belonging to the genus Colobus.
The wildlife of Uganda is composed of its flora and fauna. Uganda has a wide variety of different habitats, including mountains, hills, tropical rainforest, woodland, freshwater lakes, swamps and savanna with scattered clumps of trees. The country has a biodiverse flora and fauna reflecting this range of habitats and is known for its primates, including gorillas and chimpanzees. There are ten national parks and thirteen wildlife reserves; some 345 species of mammal and 1020 species of bird have been recorded in the country.
The montane nightjar, mountain nightjar or Abyssinian nightjar, is a species of nightjar in the family Caprimulgidae. It is native to upland regions of Central and Eastern Africa where it is a locally common species.
The Ruwenzori otter shrew is a species of semiaquatic dwarf otter shrew of the family Potamogalidae. It is found in the Democratic Republic of the Congo, Rwanda, and Uganda. Otter shrews are shrew-like afrotherian mammals found in sub-Saharan Africa. They are most closely related to the tenrecs of Madagascar.
The ursine colobus, also known as the white-thighed colobus, Geoffroy's black-and-white colobus, or the white-thighed black-and-white colobus, is a West African species of primate in the family Cercopithecidae.
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.
The wildlife of Rwanda comprising its flora and fauna, in prehistoric times, consisted of montane forest in one third the territory of present-day Rwanda. However, natural vegetation is now mostly restricted to the three national parks and four small forest reserves, with terraced agriculture dominating the rest of the country.
The little collared fruit bat is a species of megabat in the family Pteropodidae found in Angola, Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Nigeria, Rwanda, Sierra Leone, South Sudan, Togo, and Uganda. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna.
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 five different locations across Uganda and Tanzania.
This is a list of the taxonomic contributions of Major Percy Horace Gordon Powell-Cotton.
The Semliki red colobus is a type of red colobus monkey from central Africa. Historically it has been treated as a subspecies of the Central African red colobus but more recent taxonomies generally treat it as a separate species.
