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]
Taxonomy
[edit]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]
Characteristics
[edit]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]
Distribution and habitat
[edit]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]
Ecology and behaviour
[edit]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]
