Chimpanzees (Pan troglodytes) inhabit the tropical forests of central Africa. They are distributed from about 10 degrees N to 8 degrees S, and from 15 degrees W to 32 degrees E. They are found from Gambia in the west to Uganda in the east, excluding the region bordered by the Congo and Lualaba rivers in central Zaire (Congo) where their sister species, bonobos (Pan paniscus), are found.
There are three recognized subspecies of common chimpanzee. Pan troglodytes verus occurs in the western portions of the range, from Gambia to the Niger river. From the Niger river to Congo, in the central portion of the range, P. troglodytes troglodytes inhabits forested regions. In the far eastern portion of the range, from the northwestern corner of Zaire into western Uganda and Tanzania, P. troglodytes schweinfurthi is found.
