Social behaviours
Black-and-white colobus have complex sleeping patterns. They sleep in trees near a food source, which may serve to save energy. Groups seem to regularly switch up sleeping locations (suggested due to reducing risk of parasites and placement prediction) and generally do not sleep near other groups. They also tend to sleep more tightly together on nights with great visibility. They sleep in mid- to upper sections of tall trees which allows for predator watch as well as protection from ground and aerial predators while they are asleep. Although there is no obvious preference for tree type, they have often been observed in Antiaris toxicaria.
