Central African red colobus monkeys are endemic to tropical central Africa, including the Republic of Congo, the southern part of the Central African Republic, the Democratic Republic of the Congo and the southern part of South Sudan. The southern limit of the range is the Congo River, the eastern limit is the Aruwimi River and the northern limit is the savannah woodlands north of the Uele River. They are found in lowland primary forest, particularly swampy areas, open woodland and gallery forest. They spend about seventy percent of their time in the canopy, and the rest of the time on the ground. They sometimes wade into water to collect aquatic bulbs.[3]
