Mangabeys are West African Old World monkeys, with species in three of the six genera of tribe Papionini.
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 crested mangabeys are West African Old World monkeys belonging to the genus Lophocebus. They tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. Another genus of mangabeys, Cercocebus, was once thought to be very closely related, so much so that all the species were placed in one genus. However, Lophocebus 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. In 2006, the highland mangabey was moved from Lophocebus to a new genus, Rungwecebus.
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.
The white-bellied musk deer or Himalayan musk deer is a musk deer species occurring in the Himalayas of Nepal, Bhutan, India, Pakistan and China. It is listed as endangered on the IUCN Red List because of overexploitation resulting in a probable serious population decline.
The golden grosbeak, also known as golden-bellied grosbeak or southern yellow grosbeak, is a species of grosbeak in the family Cardinalidae. It is similar to, and has sometimes been considered conspecific with, the yellow grosbeak.
Ptychadena chrysogaster is a species of frog in the family Ptychadenidae. It is found in eastern Democratic Republic of the Congo (Kivu), Burundi, Rwanda, and southwestern Uganda, with an isolated record from Serengeti, Tanzania. Common names yellow-bellied ridged frog, golden-bellied rocket frog, and Rwanda grassland frog have been coined for it.
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 collared mangabey, 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.
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 black crested mangabey is a species of primate in the family Cercopithecidae. It is only found in Democratic Republic of the Congo with a small habitat extending to Angola. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The Tana River red colobus, also called the eastern red colobus, is a highly endangered species of primate in the family Cercopithecidae. It is endemic to a narrow zone of gallery forest near the Tana River in southeastern Kenya.
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".
Opdenbosch's mangabey is a subspecies of crested mangabey in the family Cercopithecidae. It has also been treated as a full species. It is found in the Democratic Republic of the Congo.
The Central Congolian lowland forests are an ecoregion within the Democratic Republic of the Congo. This is a remote, inaccessible area of low-lying dense wet forest, undergrowth and swamp in the Cuvette Centrale region of the Congo Basin south of the arc of the River Congo.
The Eastern Congolian swamp forests are a fairly intact but underresearched ecoregion of the tropical and subtropical moist broadleaf forests biome. It is located within the Democratic Republic of the Congo. This is the eastern half of one of the largest areas of swamps in the world.
The white-naped mangabey is a species of Old World monkey in the subfamily Cercopithecinae. The species is found in the forest of Burkina Faso, Ghana and Ivory Coast. The species population has been declining due to deforestation and hunting and has thus been put as an endangered species by the International Union for Conservation of Nature. The species was once considered a subspecies of the sooty mangabey but is now a separate species. This species had previously been regarded as a subspecies of Cercocebus atys, but was later raised to species status.
