Angola colobus range |
The Angola colobus (Colobus angolensis), Angolan black-and-white colobus, or Angolan colobus is a primate species of Old World monkey belonging to the genus Colobus .
There are six recognized subspecies and one undescribed subspecies from the Mahale Mountains in Tanzania: [1]
Like all black-and-white colobi, the Angola colobus has black fur and a black face, surrounded by long, white locks of hair. It also has a mantle of white hair on the shoulders. The long, thin tail can be either black or white, but the tip is always white. There is a significant regional variation in the total amount of white on the body and the length of the fur. Animals that live in the mountains have longer, thicker fur than animals from the lowlands to protect them against the cold.
The Angola colobus has a head-body length of 50 to 70 cm, with the males usually being larger than females. The tail is about 75 cm long, and the body weight varies between 9 and 20 kg.
The Angola colobus occurs in dense rainforests, both in the lowlands and coastal mountains. It lives in most of the Congo Basin, to the south and northeast of the Congo River, as far as Ruwenzori, Burundi and southwestern Uganda. The species can also be found in East Africa, especially in the interior and coastal forests of Kenya and Tanzania and in isolated mountain areas. Although the species is named after Angola, it is quite rare in that country. Of all Colobus species, the Angola colobus occurs in the southernmost latitudes. The geographical range lies south of that of the mantled guereza. It is found up to 2,415 m above sea level in Kenya. [4]
All Colobus species are very sociable and live in groups of up to several hundred animals, although most groups are much smaller. Their diet consists of mostly leaves, but also lesser amounts of fruit and seeds. [5]
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 blue monkey or diademed monkey is a species of Old World monkey native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia. It sometimes includes Sykes', silver, and golden monkeys as subspecies.
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 river Congo 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.
The Angolan genet or miombo genet is a genet species endemic to Southern Africa. It is considered common in this region and therefore listed as Least Concern in the IUCN Red List. Little is known about its ecology.
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.
The rusty-bellied brush-furred rat is a species of rodent in the family Muridae. It is found in Angola, Benin, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Kenya, Liberia, Nigeria, Sierra Leone, Tanzania, Togo, and Uganda. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical seasonally wet or flooded lowland grassland, arable land, and pastureland.
The Angola swallow is a species of swallow that is native to the Afrotropics.
The African pitta is an Afrotropical bird of the family Pittidae. It is a locally common to uncommon species, resident and migratory in the west, and an intra-African migrant between equatorial and southeastern Africa. They are elusive and hard to observe despite their brightly coloured plumage, and their loud, explosive calls are infrequently heard. The plump, somewhat thrush-like birds forage on leaf litter under the canopy of riparian or coastal forest and thickets, or in climax miombo forest. They spend much time during mornings and at dusk scratching in leaf litter or around termitaria, or may stand motionless for long periods. Following rains breeding birds call and display from the mid-canopy.
The little spotted woodpecker or green-backed woodpecker, is a species of bird in the family Picidae. It is native to large parts of tropical central Africa. It has an extensive range and is an uncommon species, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
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.
The forest giant squirrel or Stanger's squirrel is a species of rodent in the family Sciuridae found in Angola, Benin, Burundi, Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Kenya, Liberia, Nigeria, Rwanda, Sierra Leone, Tanzania, Togo, and Uganda. Its natural habitats are subtropical or tropical moist lowland forests and plantations.
The Angolan fruit bat, Angolan rousette or Silky bat is a species of megabat in the family Pteropodidae. It is found in Angola, Burundi, Cameroon, Central African Republic, Republic of Congo, Democratic Republic of Congo, Kenya, Nigeria, Rwanda, Sudan, Tanzania, Uganda, and Zambia. Its natural habitats are subtropical or tropical moist lowland forest, moist savanna, and rocky areas.
The red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon, is a species of primate in the family Cercopithecidae.
The Ruwenzori colobus, also known as Ruwenzori black-and-white colobus, is a subspecies of the Angola colobus. 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.
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.
