The sooty mangabey (Cercocebus atys) is an Old World monkey found in forests from Senegal in a margin along the coast down to the Ivory Coast. Sooty mangabeys inhabit both old growth and secondary forests as well as in flooded, dry, swamp, mangrove, and gallery forests. Sooty mangabeys are terrestrial omnivores, typically spending most of their overall time on the ground. In their foraging behaviors, sooty mangabeys typically consume fruits, invertebrates, and nuts and seeds.
