The word Colobus comes from Greek “ekolobose” and is so named because its thumb is a stump. Colobus are large monkeys with a head and body length longer at 78cm. Fur is black with white or greyish whiskers and epaulettes and a white tail. Thumb is absent or greatly reduced. Newborn infants are pure white, obtaining their adult markings by 3 – 4 months. Colobus monkeys live in African forests in groups of 3 – 15 individuals within a well defined territory, while the red colobus live in larger groups with many males. They are arboreal and seldom come to the ground, except occasionally to pick up fallen fruit.
Their diet consists mainly of both young and mature leaves, but they also eat fruit, flowers and woody twigs.
Colobus monkeys can be found in Bwindi Impenetrable National park, Semiliki National park, Kibale forest National park all in Uganda and then Nyungwe Forest National park in Rwanda with a semi-habituated troop of 400 species, resident in the forest.
