Smoky Mangabey

Sooty mangabeys are gray-colored primates with a lighter-colored chest and stomach. Their faces are typically grayish pink, with darker fur along the forehead and ears; given their diet of hard seeds and nuts, sooty mangabeys are observed to have strong molars. Sooty mangabeys also show sexual dimorphism; males typically weigh about 10–11 kg (22–24 lb), while females are typically smaller at about 5–6 kg (11–13 lb).

The sooty mangabey is native to tropical West Africa, being found in Guinea, Guinea-Bissau, Liberia, Senegal, Sierra Leone, and Ivory Coast. Sooty mangabeys inhabit both old growth and secondary forests as well as in flooded, dry, swamp, mangrove, and gallery forests. Farmland can also be inhabited or put to use by the sooty

Sooty mangabeys are terrestrial omnivores, typically spending around 75% of their overall time on the ground (~85% of travel time and ~71% of foraging time). In their foraging behaviors, sooty mangabeys typically consume fruits (~20% of diet), invertebrates (~13% of diet), and nuts and seeds (>55% of diet). In acquiring nuts, sooty mangabeys have been observed scavenging the remains of coula and panda nuts cracked by chimpanzees and red river hogs, potentially using either the sound of cracking nuts or social networks to identify sites of remnants.
