The crested mona monkey, also known as the crowned guenon, crowned monkey, golden-bellied guenon, or golden-bellied monkey, (Cercopithecus pogonias), is a species of African primate in the family Cercopithecidae found in west central Africa.



The crested mona monkey is a medium-sized, long tailed arboreal monkey with the females being smaller than the males but showing similar colouration and pattern of coat. They have a brown coat speckled with grey which becomes black on its lower arms and legs and on the base of its long tail. The rump, belly and the insides of the legs are golden-yellow contrasting with the rest of the fur. The males have a distinctive blue scrotum. Their faces are mainly dark blue with a pink muzzle. Around the face the fur is yellow marked with a wide black stripes which runs from the beside the eyes over to the temples and across the centre of the forehead where it forms the characteristic small crest which gives this species its common name. [4] [5]


Western central Africa from the Cross River in Nigeria and southern Cameroon south to Cabinda, Angola, including Bioko Island, and east into the Central African Republic, eastern Congo and the northern Democratic Republic of Congo. [5]


The Crested mona monkey occurs in mature lowland rainforest, in both primary and secondary forest, where there is a well developed canopy and with a clear understorey. Will also occur in flooded forest but avoids small forest patches, gallery forests and open secondary forest with a dense understorey. [5]


The crested mona monkey is a highly vocal species with a wide repertoire of calls. Both males and females have vocal sacs which are inflated to be used as resonators. A typical call is the booming call made by the adult male which can be heard more than 200m away. Social interactions include tail twining between resting monkeys and a ritualised head display. [5]

The crested mona monkey is an agile species, which crosses large gaps between trees by jumping. They are normally found in groups of between 8 and 20 individuals which are typically made up of a single male, several females and their dependent offspring. Groups are highly vocal, with the males producing the loud, "boom" mentioned above announcing their presence and status, there is also a sharp hacking call which is used as an alarm. The dominant males are able to establish groups, and therefore the lives of most males are rather solitary and are marked by an absence of social contact. Surprisingly, this appears to lead to some males joining groups of other monkeys such as the black colobus Colobus satanas, where these solitary males can form strong group bonds with the non conspecific monkeys, possibly resulting in a permanent loss of mating opportunities. The social groups of crested mona monkeys will also associate with other guenon species, especially with moustached guenon Cercopithecus cephus and greater spot-nosed monkey Cercopithecus nictitans . These large mixed-species groups grant the monkeys' increasedprotection from predation, as the greater number of eyes on the sky means that the spotting of predators such as birds of prey is more likely, and it also facilitates the sharing of information between groups about the best foraging sites. [6]

The crested mona monkey is mainly frugivorous but invertebrates are also frequently taken, along with small quantities of leaves. Unlike most guenons, populations of the crested mona monkey in the northern parts of its range are known to migrate over long distances to forage for seasonally abundant food supplies. The crested mona monkey has a polygynous mating system where the dominant male in each group has exclusive breeding access to all the females in that group. Breeding seem to take place at any time of year, and the females give birth to a single baby after a gestation period of roughly five months. [6]


This species sits within the mona superspecies grouping within Cercopithecus . [5] There does not seem to be a consensus around how many subspecies of the crested mona monkey are recognised and some which were formerly considered subspecies of this species are now regarded as species in their own right, e.g. Wolf's mona monkey Cercopithecus wolfi and Dent's mona monkey Cercopithecus denti. Three subspecies appear to be the most widely accepted treatment. [3]

The subspecies and their ranges are: [5]

The subspecies schwarzianus is not now generally recognised. [5]

Old World monkey Family of mammals

Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae. Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons, macaques, and mabahlls. Common names for other Old World monkeys include the talapoin, guenon, colobus, douc, vervet, gelada, mangabey, langur, mandrill, surili (Presbytis), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 55 million years ago.

Guenon Genus of Old World monkeys

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.

Blue monkey Species of Old World monkey

The blue monkey or diademed monkey is a species of Old World monkey native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia. It sometimes includes Sykes', silver, and golden monkeys as subspecies.

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.

Preusss monkey Species of Old World monkey

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 Brazzas monkey Species of Old World 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.

Mona monkey Species of Old World monkey

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 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.

Wildlife of Cameroon

The wildlife of Cameroon is composed of its flora and fauna. Bordering Nigeria, it is considered one of the wettest parts of Africa and records Africa's second highest concentration of biodiversity. To preserve its wildlife, Cameroon has more than 20 protected reserves comprising national parks, zoos, forest reserves and sanctuaries. The protected areas were first created in the northern region under the colonial administration in 1932; the first two reserves established were Mozogo Gokoro Reserve and the Bénoué Reserve, which was followed by the Waza Reserve on 24 March 1934. The coverage of reserves was initially about 4 percent of the country's area, rising to 12 percent; the administration proposes to cover 30 percent of the land area.
