Colobus exhibit, at the south end of the Zoo near the maned wolf exhibit, and the Rare Animal Conservation Center.
The colobus live in groups of up to 10 individuals. They are diurnal and arboreal, spending half their day resting in trees or on the ground and the other half of their day foraging and feeding.
Black and white colobus can live up to 25 years.
Gestation is ~158 days and the young are born completely white.
A baby is born completely white and will slowly transition to the adult black and white coloring over a three month span of time. The colobus practice "allo maternal care". This type of care involves several females in the troop sharing responsibility for the care and raising of the offspring.
Males are 24 in (60 cm) and Females are 22 in (56 cm).
Males weigh 20-31 lb (9-14 kg) and Females weigh 18-20 lb (8-9 kg).
Black and white colobus monkeys are strict leaf eaters. In the wild they like tender young leaves found in treetops. Their unique, complex digestive system allows them to consume some vegetation that other monkeys cannot. At the Zoo, they are offered a base diet of primate biscuit designed for leaf eating primates. The enrichment portion of the diet includes a variety of leafy greens and vegetables. During the summer a portion of their enrichment diet includes a variety of leaves harvested from the Zoo’s browse farm. The leaves are analyzed for nutrient composition and formulated into diet.
Ethiopia, Nigeria, Kenya, Tanzania among others.
