Grey-Cheeked Mangabey, Kibale National Park, UgandaThe grey-cheeked mangabey is an old world monkey that lives in the forests of central Africa. I encountered this one in Kibale National Park in Uganda, the eastern edge of its range. They resemble baboons, but if you look at this guy’s face, you’ll see they also resemble the Grinch.
