The black and white colobus monkey lives in the uppermost branches of tropical forests, woodlands, and wooded grasslands, sometimes traveling on the ground. They are located from west central and east Africa:eastern Nigeria to Ethiopia and Tanzania. Their coats are glossy black, while faces and rumps are surrounded by white. There are u-shaped white mantles on the sides and rear of their backs, and their  tails are white at the end. Baby colobus monkeys are all white. Their bodies are from eighteen to twenty-eight inches long, and their tails are from twenty to thirty-five inches long. They weigh from twelve to thirty-two pounds. Their digestive systems are designed to process leaves, but the monkeys will sometimes eat flowers, twigs, buds, seeds, and shoots. Fruit makes up about one-third of their diet. Females produce a single baby after about five months of gestation. Offspring are produced about every twenty months. Their life span captivity is twenty-three years and older. Logging and habitat conversion for farming are the biggest threats to the black and white colobus monkeys' habitat.
