Diana Monkey at Zoo Leipzig, also known as "Leipzig Zoological Garden" (Germany)
The Diana Monkey is an Old World monkey found in West Africa, from Sierra Leone to Côte d'Ivoire. They are generally black or dark grey, but have a white throat, crescent-shaped browband, ruff and beard; the browband gave the species its common name, since it was held to resemble the crescent on the brow of the goddess Diana. The monkeys' underarms are also white, and they have a white stripe down their thighs, while the backs of their thighs, and their lower backs, are a chestnut colour. Apart from the browband, ruff and beard, and some fringes on their limbs, their fur is short and sleek in appearance. The Diana monkey is found in the primary forests, and does not thrive in secondary forests. It is active during the day. It feeds at all levels of the canopy, and rarely comes down to the ground. Diana monkeys retreat to the upper levels of the trees at night, though they do not make nests. They feed mainly on fruit and insects, but also take flowers, young leaves and invertebrates.
