The silver monkey ( Cercopithecus doggetti ) is a primate of the genus monkeys ( Cercopithecus ) within the family of Cercopithecidae (Cercopithecidae). It was only recognized as a separate species in 2001, but is still often listed as a subspecies of the diademed monkey ( C. mitis ). Its small distribution area includes a region located on Lake Eduard and the northern tip of Lake Tanganyika in the east of the Democratic Republic of the Congo , parts of Rwanda and Burundi , southern Uganda and extends to northwestern Tanzania ( Kagera ).

features

The silver monkey resembles the diademed monkey, but differs in its silver-gray back fur. The rest of the fur is usually colored blue-gray. The top of the head, the nape of the neck and the last third of the tail are black. The hair is gray at the base and then alternately colored yellow and black five to nine times. So far, body measurements have only been taken from a single adult female. The animal had a head-to-torso length of 48.7 cm and a 65.5 cm long tail.

Way of life

Little research has been done on the silver monkey. They are diurnal tree dwellers and live in primary , secondary and mountain forests (up to an altitude of 2700 meters) in groups consisting of one male with several females or several males, several females and the offspring belonging to them. The group size is between 15 and over 60 animals. In the Nyungwe Forest , the territories that the groups inhabited were about 25 hectares. More than 50% of their diet consists of fruits, and they also consume many insects. Leaves, seeds, flowers, mushrooms, tree sap, mosses and lichens make up the rest of their diet. Animals that live in swamp areas or gallery forests also eat the soft stems of the papyrus . Insects that are eaten include termites , grasshoppers , ants, beetle larvae found in rotting wood, and cicadas.

Since the silver monkey is also found in some protected areas such as the Nyungwe Forest in southwestern Rwanda, the Gombe Stream National Park in Tanzania and in the Bwindi Impenetrable National Park and Mgahinga Gorilla National Park in Uganda, the IUCN lists the silver monkey as harmless.
