The collared mangabey (Cercocebus torquatus), also called red-capped mangabey and white-collared mangabey, [3] 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. [1]
The collared mangabey has grey fur covering its body, but its common names refer to the colours on its head and neck. [4] Its prominent chestnut-red cap gives it the name red-capped, and its white collar gives it the names collared and white-collared. [4] Its ears are black and it has striking white eyelids, which is why some refer to it as the "four-eyed monkey". [4] It has a dark grey tail that exceeds the length of the body and is often held with the white tip over its head. [4] It has long molars and very large incisors. [5] The average body mass for captive individuals ranges from 9 to 10 kg (20 to 22 lb) for males and 7.5 to 8.6 kg (17 to 19 lb) for females. [5] Head-body length is 47–67 cm (19–26 in) in males and 45–60 cm (18–24 in) in females. [4]
The collared mangabey is found in coastal, swamp, mangrove, and valley forests, from western Nigeria, east and south into Cameroon, and throughout Equatorial Guinea, and Gabon, and on the Gabon-Congo border by the Atlantic shore. [2]
The collared mangabey lives in large groups of 10 to 35 individuals including several males. [6] Vocal communication in the form of cackles and barks are used to keep the group in contact and signal their position to other groups. It has a diet of fruits and seeds, but also eats leaves, foliage, flowers, invertebrates, mushrooms, dung, and gum. [5] [6] The collared mangabey has no defined breeding season, it reaches sexual maturity at five to seven years, and has an average gestation period of 170 days. [6]
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. [7]
The collared mangabey is listed as endangered on the IUCN Red List due to habitat loss and hunting for bushmeat. [2] 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. [2]
Bushmeat is meat from wildlife species that are hunted for human consumption. Bushmeat represents a primary source of animal protein and a cash-earning commodity in poor and rural communities of humid tropical forest regions of the world.
The mandrill is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. It is the largest monkey in the world. Its closest living relative is the drill, with which it shares the genus Mandrillus. Both species were traditionally thought to be baboons, but further evidence has shown that they are more closely related to white-eyelid mangabeys.
Mandrillus is a genus of large Old World monkeys distributed throughout central and southern Africa, consisting of two species: M. sphinx and M. leucophaeus, the mandrill and drill, respectively. Mandrillus, originally placed under the genus Papio as a type of baboon, is closely related to the genus Cercocebus. They are characterised by their large builds, elongated snouts with furrows on each side, and stub tails. Both species occupy the west central region of Africa and live primarily on the ground. They are frugivores, consuming both meat and plants, with a preference for plants. M. sphinx is classified as vulnerable and M. leucophaeus as endangered on the IUCN Red List of Threatened Species.
The African palm civet, also known as the two-spotted palm civet, is a small feliform mammal widely distributed in sub-Saharan Africa. It is listed as least concern on the IUCN Red List.
The grey-cheeked mangabey, also known as the white-cheeked mangabey, is an Old World monkey found in the forests of Central Africa. It ranges from Cameroon down to Gabon. The grey-cheeked mangabey is a dark monkey, looking in shape overall like a small, hairy baboon. Its thick brown fur is almost black in its forest home, with a slightly rufus/golden mane around the neck. The sexes are similar, with the males slightly larger than the females.
The kipunji, also known as the highland mangabey, is a species of Old World monkey that lives in the highland forests of Tanzania. The kipunji has a unique call, described as a 'honk-bark', which distinguishes it from its relatives, the grey-cheeked mangabey and the black crested mangabey, whose calls are described as 'whoop-gobbles'.
The sooty mangabey is an Old World monkey found in forests from Senegal in a margin along the coast down to the Ivory Coast.
The white-eyelid mangabeys are African Old World monkeys belonging to the genus Cercocebus. They are characterized by their bare upper eyelids, which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur. The other two genera of mangabeys, Lophocebus and Rungwecebus, were once thought to be very closely related to Cercocebus, so much so that all the species were placed in one genus, but Lophocebus and Rungwecebus species are now understood to be more closely related to the baboons in genus Papio, while the Cercocebus species are more closely related to the mandrill.
De Brazza's monkey is an Old World monkey endemic to the riverine and swamp forests of central Africa. The largest species in the guenon family, it is one of the most widespread arboreal African primates. Aside from size, it can be differentiated from other Cercopithecus monkeys by its orange diadem and white beard. Due to its cryptic nature, the species is not well documented in all of its habitats but has shown unique traits, such as pair-bonding and aggressive behavior towards other guenons.
The Cross–Sanaga–Bioko coastal forests are a tropical moist broadleaf forest ecoregion of west-central Africa. This is a lush forest, rich in flora and birdlife.
The black colobus, or satanic black colobus, is a species of Old World monkey belonging to the genus Colobus. The species is found in a small area of western central Africa. Black colobuses are large, completely covered with black fur, and like all other Colobus monkeys, do not have a thumb. The species has faced large declines in population due to habitat destruction and hunting by humans, and was consequently listed as Vulnerable on the IUCN Red List in 1994.
The Tana River mangabey is a highly endangered species of primate in the family Cercopithecidae. Some authorities have included the taxa agilis and sanjei as subspecies of this species, while others award these full species status.
The moustached guenon or moustached monkey is a species of primate in the family Cercopithecidae. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon.
The red-eared guenon, also called red-eared monkey or russet-eared guenon, is a primate species in the family Cercopithecidae. It is native to subtropical and tropical moist lowland forests in Cameroon, Equatorial Guinea and Nigeria. It is listed as Vulnerable on the IUCN Red List and is threatened by habitat loss, illegal bushmeat hunting and pet trade.
The Gabon bushbaby is a species of primate in the family Galagidae found in Cameroon, Gabon, and the Republic of the Congo. Its head and body length is 8.5 in with a 10-in tail, and it weighs about 10 oz. It lives in evergreen tropical rainforests and eats primarily fallen fruit, but also some arthropods.
The agile mangabey is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo. Until 1978, it was considered a subspecies of the Tana River mangabey. More recently, the golden-bellied mangabey has been considered a separate species instead of a subspecies of the agile mangabey.
The Sanje mangabey is a highly endangered Old World monkey of the white-eyelid mangabey group from the Eastern Arc Mountains in Tanzania. They are about 50–65 centimetres (20–26 in) in length, excluding the tail, and their body colour is greyish. Fruit makes up about 70% of their diet. They live in valley forests and on mountain slopes, but are mostly ground-dwelling, which makes them susceptible to hunting and poaching. Their habitat is being degraded, and the International Union for Conservation of Nature has assessed their conservation status as being "endangered".
Douala-Edéa National Park, formerly known as Douala-Edéa Wildlife Reserve, is a national park in the Littoral Region of Cameroon.
The Niger Delta red colobus is a critically endangered species of colobus monkey endemic to the western part of the Niger Delta. It is threatened by hunting and habitat loss.
The drill is a primate of the family Cercopithecidae, related to baboons and even more closely to mandrills.
