This was really interesting. This poor little mangabey was separated from its mom and troupe and was the only mangabey in a group of guenons and colobus, my guide who has studied mangabey's for 15 years had never seen this.
The sooty mangabey (Cercocebus atys) is an Old World monkey found in forests from Senegal east to Ghana. It is famous for being believed to be the monkey that HIV-2 might have originated in before jumping species. While overall rated as Vulnerable, the eastern race lunulatus, also known as the white-crowned or white-collared mangabey (leading to easy confusion with the collared mangabey), is considered Endangered by the IUCN.
