They spend around half their time eating leafy greens and the other half eating seeds and fruits. These monkeys do not climb into the treetops and only rarely come down to the ground. Donate now. [10] However, more recent observations have shown variation in structure and the number of males within groups, with one species forming multi-male, multifemale groups in a multilevel society, and in some populations supergroups form exceeding 500 individuals. Individuals of the genus Colobus are typically found in tropical rain forests (lowland and montane types) of Africa, in the countries of Senegal, Ethiopia, Tanzania, Congo, Malawi, Uganda and Zambia. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. A female will give birth once every 20 months, on average. The king colobus (Colobus polykomos), also known as the western black-and-white colobus, is native to the tropical lowland and montane rainforests on the western coast of Africa, from Gambia to Cte dIvoire.
