Mangabey

Cercocebus torquatus, Colchester Zoo, Essex, England - 20080211

Mangabey refers to a group of Old World monkeys belonging to the genus Cercocebus and Lophocebus, which are part of the family Cercopithecidae. These primates are native to Africa, where they inhabit a range of environments from tropical rainforests to swamps and bamboo forests. Mangabeys are known for their diverse size and color, ranging from grey to yellowish and dark brown. They are characterized by their long tails, which are often longer than their bodies, and their distinctive facial appearances, which vary among species.

Description

Mangabeys are medium to large-sized monkeys with long limbs and tails. Their fur color can vary significantly among species, from light grey to yellowish-grey and dark brown. They have pronounced cheek pouches, which allow them to store food while foraging. Mangabeys are diurnal and primarily arboreal, although some species spend considerable time on the ground. Their diet mainly consists of fruits, seeds, insects, and occasionally small vertebrates.

Classification

The classification of mangabeys has been subject to revisions. Traditionally, they were divided into two genera: Cercocebus, which includes the so-called white-eyelid mangabeys, and Lophocebus, which comprises the crested mangabeys. However, genetic studies have shown that these groups are not as closely related as previously thought, leading to a reevaluation of their classification.

Genera and Species

• Cercocebus: This genus includes species such as the Sooty Mangabey (Cercocebus atys) and the Collared Mangabey (Cercocebus torquatus), among others. These species are generally larger and have a more terrestrial lifestyle.
• Lophocebus: This genus includes the Grey-cheeked Mangabey (Lophocebus albigena) and the Black Crested Mangabey (Lophocebus aterrimus), among others. Members of this genus tend to have a more arboreal lifestyle and are characterized by their distinctive crests.

Habitat and Distribution

Mangabeys are found across a wide range of habitats in sub-Saharan Africa. They are adaptable and can live in various environments, including lowland tropical forests, montane forests, swamp forests, and bamboo groves. Their distribution spans from Senegal and Ethiopia in the east to Angola and Kenya in the west.

Behavior and Ecology

Mangabeys are social animals and live in groups that can number from a few individuals to over a hundred, depending on the species and the environment. They have a complex social structure and communicate using a variety of vocalizations, facial expressions, and body postures. Mangabeys are omnivorous, with a diet that includes fruits, leaves, seeds, insects, and small animals. They play a significant role in their ecosystems as seed dispersers and as prey for larger predators.

Conservation Status

The conservation status of mangabey species varies. Some species are classified as Critically Endangered or Endangered due to habitat destruction, hunting, and the pet trade. Conservation efforts are underway in various parts of Africa to protect these primates and their habitats.
