|Sooty Mangabey range|
The sooty mangabey (Cercocebus atys) is an Old World monkey found in forests from Senegal east to Ghana. While overall rated as Vulnerable, the eastern race lunulatus, also known as the white-crowned, white-naped or white-collared mangabey (leading to easy confusion with the collared mangabey), is considered Endangered by the IUCN.
Habitat and ecology 
The sooty mangabey lives in both old growth and secondary forests as well as in flooded, dry, swamp, mangrove, and gallery forests. The primate is arboreal and diurnal. They are omnivores whose diet includes primarily fruits and seeds, sometimes feeding on small animals. They live in social groups of four to twelve individuals, but occasionally groups as large as 95 individuals have been recorded.

Sooty mangabeys are naturally infected with a strain of Simian Immunodeficiency Virus (SIV), known as SIVsmm. Due to extensive human-mangabey contact in sub-Saharan Africa, SIVsmm has jumped from this species into humans on multiple occasions, resulting in HIV-2 virus. The HIV-1 strain by contrast came from the common chimpanzee strain of SIV.
