Wolf's mona monkey

Wolf's mona monkey, Cercopithecus wolfi, also called Wolf's guenon, is a colourful Old World monkey of central Africa, found chiefly between the Democratic Republic of the Congo and Uganda in primary and secondary lowland rainforest and swamp forest. It was first described in 1891 from a living animal in the Dresden zoo, brought from central west Africa by Dr Ludwig Wolf, and was once treated as a subspecies of the crested mona monkey. It is dark grey with a red saddle on its back, and two subspecies are separated by a large area of swamp forest. Males weigh about 4.5 kilograms and females about 2.5. It lives in groups with one male and several females, feeds mainly on fruit with some seeds and insects, and often travels with red-tailed monkeys and black crested mangabeys.
