Collared mangabey видео
The collared mangabey (Cercocebus torquatus), also called red-capped mangabey and white-collared mangabey is a species of primate in the family Cercopithecidae of Old World monkeys. It formerly included the sooty mangabey as a subspecies. As presently defined, the collared mangabey is monotypic.
Appearance
Cercocebus torquatus is a species of catarrhine primate of the family Cercopithecidae. Cercocebus torquatus is a fairly large primate: males can weigh up to 18 kg and females 12 kg. Its fur is short and dark smoky, its face is yellowish brown and it has a dark brown "cap" of hair on its head and a pinkish face.
Area habitat and nutrition
Cercocebus torquatus are common in Cameroon, Equatorial Guinea, Gabon and Nigeria. These arboreal primates inhabit forests, mainly in the lower levels, and are often found in humid forests. They spend a lot of time on the ground and only climb trees when resting or in danger. These primates use trees for feeding, sleeping shelter and protection from predators. Interestingly, these monkeys can swim. They have strong legs that can crack nuts. The diet of Cercocebus torquatus consists mainly of fruits and plant seeds, however, invertebrates and small vertebrate animals make up 1-30% of their diet. The main enemies of Cercocebus torquatus redfoots are eagles and leopards.
Social behaviour
Cercocebus torquatus is usually kept in groups of 10 to 35 individuals. There may be several males in the groups, and most of them live together peacefully, with no signs of dominance over others. Males express their mood through tail movements: their position serves as a peculiar form of communication between group members.
Reproduction
Cercocebus torquatus reaches sexual maturity at the age of 5-7 years. Cercocebus torquatus is not thought to have a defined breeding period. Gestation lasts an average of 5.5 months, after which a young is born. At two weeks of age, it begins to eat hard fruit. From about four to six weeks of age, the young move around clinging to their mother's belly and later lead a relatively independent life, but they will not be completely separated from their mother until 14 weeks of age and will cling to her again at the slightest danger or when moving for long periods. The maximum lifespan of the smoky Cercocebus torquatus is 18 years.
Threats
In 2006, it was estimated that annually about 3,000 collared mangabeys are hunted in the Cross-Sanaga-Bioko coastal forests for the bushmeat trade.
Conservation
The collared mangabey is listed as endangered on the IUCN Red List due to habitat loss and hunting for bushmeat. It is also listed on Appendix II of CITES and on Class B of the African Convention on the Conservation of Nature and Natural Resources.
