Black-and-white colobus in Swahili: mbega mweupe (Colobus guereza)
Length (excluding tail): 60–70 cm; weight: 10–16 kg. This beautiful jet-black monkey has bold white facial markings and beard, a long white tail and in some races white sides and shoulders. Almost exclusively arboreal, it is capable of jumping up to 30 metres, a spectacular sight with fluffy white tail streaming behind. Several races have been described, and most authorities recognised more than one species. The black-and-white colobus is a common resident of forests in Tanzania, often seen in the forest zone of Kilimanjaro, in Arusha National Park, and along the Grumeti River as it flows through the Western corridor of the Serengeti.
