Maxwell’s duiker occurs in the lowland forest area from Senegal to south-western Nigeria (Wilson & Reeder, 1993), and is present in Benin, Burkina Faso, Gambia, Ghana, Guinea, Guinea Bissau, Ivory Coast, Liberia, Nigeria, Togo (East, 1996). Its eastern limit is represented by the Niger River , to the west of which the allopatric species C. monticola occurs ( Ralls, 1973). The first rough distribution map was obtained from Ralls (1973), and updated on the basis of the more recent information found in country maps from East (1990), as indicated by Dr. R. East (23 June '97)
Categorical-discrete (CD) distribution model
Primarily found in rainforest, the species appears to be common in riverine forests and forest patches in savanna woodland zones. It is also reported to occur in moister savannas and other dense vegetation near permanent water (Coe, 1975; East, 1990; Stuart & Stuart, 1997; Ralls, 1973; Kingdon, 1997).
