Sierra Leone to south-western Togo and central Nigeria, south of the Benue River.
Forest and abandoned agricultural areas.
Young leaves, fruit and seeds.
The typical group size is 10-18, and the sexes are mixed. The home range is about 74 acres, and much of the time is spent seeking food because of the low-energy diet. Social interaction is minimised.
Females solicit mating from males, and this can take place at any time of year, although there is a peak of births when food is most available. A single youngster is born, with fur and open eyes. The mother, uniquely, carries it in her mouth rather than letting it cling to her belly. Other females in the group frequently handle and suckle the youngster. Adulthood is reached between 6-10 months, and sexual maturity is at about 4 years of age.
