The Guenon are a Genus of Old World monkey, comprised of around 26 species found across Africa. The name is French, and translates as "monkey". They are generally characterised by their long back legs, rounded heads and cheek pouches. Many species have additional facial adornments in the form of beards or moustaches and striking colouration. This fellow is a Red-tailed Guenon. Most species live in large groups, mainly comprised of females but with at least one resident male. Males form their own, smaller, groups. They forage through the treetops, following an omnivorous diet of leaves, fruit, invertebrates, seeds and even small vertebrates.
