Black-and-white colobuses (or colobi) are Old World monkeys of the genus Colobus, native to Africa. They are closely related to the red colobus monkeys of genus Piliocolobus.[1] There are five species of this monkey, and at least eight subspecies.[1] They are generally found in high-density forests where they forage on leaves, flowers and fruit. Social groups of colobus are diverse, varying from group to group.[2] Resident-egalitarian and allomothering relationships have been observed among the female population.[3] Complex behaviours have also been observed in this species, including greeting rituals[2] and varying group sleeping patterns.[4] Colobi play a significant role in seed dispersal.
