The Temminck colobus monkey ( Piliocolobus temminckii ) is a species of primate from the genus of the red colobus monkey , which occurs in Gambia , in the south of Senegal , in Guinea-Bissau and in the immediately adjacent areas of Guinea .
features
The Temminck colobus monkey is only slightly smaller than the closely related West African colobus monkey ( Piliocolobus badius ). It is medium gray in color on the back and the outside of the upper arms and thighs. The remaining outer sides of the limbs, the sides of the head, the backs of the hands and feet are colored orange-red. The chest, abdomen and the insides of the limbs are whitish. The face is dark, there is a rosy ring around the eyes. The females show their willingness to mate during their fertile days by a rosy swelling of the rule .
Way of life
Temminck colobus monkeys live in forest islands in the savannah, mangrove swamps , tree-lined cultivated land, dry and gallery forests , usually always near open water and often in the company of the western green monkey ( Chlorocebus sabaeus ). They live in groups of usually 12 to 28 specimens. In exceptional cases, the groups can contain up to 60 animals. In most cases they stay in the trees at heights of more than ten meters. They prefer to feed on leaves, sprouts, fruits, flowers, buds and seeds. As the deforestation progresses, however, they go to look for their food on the ground and eat grass, grass seeds and herbs. After a gestation of around 175 days, the females have a single young animal that has a similar but lighter coat color than the adults. Well-known predators include free-roaming dogs, the spotted hyena ( Crocuta crocuta ) and the northern rock python ( Python sebae ).
Systematics
The Temminck colobus monkey was described as Colobus temminckii by the German zoologist Heinrich Kuhl in 1820 . Later it was assigned to the West African colobus monkey ( Piliocolobus badius ) as a subspecies. In 2013 the shape was raised to species rank in the Primate Volume of the Handbook of the Mammals of the World . From the West African colobus monkey, which has a similar coloration - but without a light underside - the line of the Temminck colobus monkey probably separated about 300,000 years ago. Today both species of apes are separated from each other by a distribution gap in Guinea.
Danger
The IUCN lists the Temminck colobus monkey in its Red List of Endangered Species as endangered. The animals are heavily hunted to obtain bushmeat . In Senegal there are probably only 400 to 500 animals or fewer in the Saloum Delta and probably fewer than 100 in the Niokolo-Koba National Park to the southeast . In Basse Casamance National Park , they are gone. In Gambia they still live in various national parks, e.g. B. in the Abuko Nature Reserve and in the Bijilo Forest Park .
