|Red-eared guenon range|
The red-eared guenon, red-eared monkey, or russet-eared guenon (Cercopithecus erythrotis) is a species of primate in the family Cercopithecidae. It is found in Cameroon, Equatorial Guinea, and Nigeria. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss,illegal bushmeat hunting and pet trade.
The red-eared guenon is a small, colourful monkey with distinctive facial markings which involve blue fur around its eyes, a brick-red nose and ears, and yellow cheeks. The silky fur on the body consists of banded brown and pale hairs with grey limbs and a long, red tail. The long tails are partially prehensile and are used by infants to cling to the female. The red-eared guenon is an unobtrusive species which produces a quiet trill, unlike the loud long-distance calls made by other guenons. mm head and bodylength, with a 609 mm long tail, females are smaller with a mean head and body length of 384 mm and an average tail length of 553 mm.Males average 420
There are two recognised subspecies, which are listed below with their distributions:
The red-eared guenon is found in primary and secondary lowland tropical and sub-montane moist forest, and sometimes lives in close proximity to humans, as on Bioko.
The red-eared guenon is omnivorous and has been recorded eating fruit, leaves, shoots and insects, the latter are important for nutrition, especially for pregnant and lactating females. The red-eared guenon normally forms groups consisting of at least one adult male and around ten females with young which are not as hierarchical as some primate societies. They are territorial but they usually avoid conflict with other groups. The breeding biology of red-eared guenons is little known but similar species give birth to a single infant every one to three years, with pregnancy taking five or six months.
The red-eared guenon is threatened by deforestation and by the bushmeat trade, particularly on Bioko, where it is frequently recorded in bushmeat market in Malabo.In 2006, it was estimated that about 3,400 red-eared guenons are hunted yearly in the Cross-Sanaga-Bioko coastal forests for the bushmeat trade.
The guenons are the genus Cercopithecus of Old World monkeys. Not all members of this genus have the word "guenon" in their common names; also, because of changes in scientific classification, some monkeys in other genera may have common names that include the word "guenon". Nonetheless, the use of the term guenon for monkeys of this genus is widely accepted.
Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako or by its indigenous name Mongo ma Ndemi. It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and the 31st-most prominent in the world.
The white-throated guenon, also known as the red-bellied monkey and the red-bellied guenon, is a diurnal primate that lives on trees of rainforests or tropical areas of Nigeria and Benin.
Sclater's guenon, also known as Sclater's monkey and the Nigerian monkey, is an Old World monkey that was first described by Reginald Innes Pocock in 1904 and named after Philip Sclater. It is an arboreal and diurnal primate that lives in the forests of southern Nigeria. It should not be confused with the closely related species, the white-throated guenon, which occurs in Nigeria and Benin. Sclater's guenon was formerly classified as a subspecies of the red-eared guenon.
The Preuss's monkey, also known as Preuss's guenon, is a diurnal primate that lives terrestrially in mountainous forests of eastern Nigeria, western Cameroon and Bioko in Equatorial Guinea. It was formerly classified as a subspecies of the L'Hoest's monkey.
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 mona monkey is an Old World monkey that lives in western Africa between Ghana and Cameroon. The mona monkey can also be found on the island of Grenada as it was transported to the island aboard slave ships headed to the New World during the 18th century. This guenon lives in groups of up to thirty-five in forests. It mainly feeds on fruit, but sometimes eats insects and leaves. The mona monkey has brown agouti fur with a white rump. Its tail and legs are black and the face is blue-grey with a dark stripe across the face. The mona monkey carries food in cheek pouches.
The Cross-Sanaga-Bioko coastal forests are a tropical moist broadleaf forest ecoregion of west-central Africa. This is 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 Cameroonian Highlands forests are a montane tropical moist broadleaf forest ecoregion located on the range of mountains that runs inland from the Gulf of Guinea and forms the border between Cameroon and Nigeria. This is an area of forest and grassland which is becoming increasingly more populous as more and more land is cleared for agriculture.
The collared mangabey, also known as the red-capped mangabey, or the 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.
The lesser spot-nosed monkey, lesser spot-nosed guenon, lesser white-nosed guenon, or lesser white-nosed monkey is a species of primate in the family Cercopithecidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, Togo, Guinea-Bissau, and possibly Senegal.
The crested mona monkey, also known as the crowned guenon, crowned monkey, golden-bellied guenon, or golden-bellied monkey,, is a species of African primate in the family Cercopithecidae found in west central Africa.
The northern needle-clawed bushbaby is a species of strepsirrhine primate in the family Galagidae. It is found in the coastal region of Cameroon and Nigeria, and on the island of Bioko, Equatorial Guinea in lower-elevation forests that provide its specialized diet of tree gum and resins.
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.
Allochrocebus is a primate genus including the terrestrial guenons: the L'Hoest's monkey, the Preuss's monkey, and the sun-tailed monkey.
The drill is a primate of the family Cercopithecidae, related to baboons and even more closely to mandrills.
The red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon is a species of primate in the family Cercopithecidae.
