Distribution

Geography

Western red colobuses are native to tropical West Africa. Their range includes various fragmentary populations in Sierra Leone, and contiguous populations in Liberia, Guinea, and the western Ivory Coast. These monkeys are typically found in primary rainforest, but also inhabit the secondary forest, gallery forest, mangroves, woodland savanna, a shrub savanna.

Habits and Lifestyle

Western red colobuses live high in trees and only rarely descend to the forest’s floor. They are active during the day and spend their time traveling, resting, playing, feeding, and grooming. These monkeys live in colonies of between 12 and 80 members. There are usually several males and up to three times this number of adult females. Colonies are very territorial and there is a social hierarchy, giving access to food, space, and grooming.

Population number

There is no overall population estimate available for the Western red colobus. However, there are estimates of its populations in specific areas: 97,000 individuals in Côte d’Ivoire and over 5,000 individuals in Gola Rainforest National Park (Sierra Leone). Currently, the Western red colobus is classified as Endangered (EN) on the IUCN Red List and its numbers today are decreasing.

Ecological niche
