L’Hoest’s Monkey (Cecopithecus lhoesti)
L’Hoest’s Monkey is semi-terrestrial and restricted to the lowland, submontane and montane forests of the Albertine Rift in eastern DRC and western Burundi, Rwanda and Uganda. This handsome guenon is less well known and more difficult to see than most of its relatives, largely because of its preference for dense secondary forest and its terrestrial habits.
This monkey has a black face and backward-projecting white whiskers that partially cover its ears, and is the only guenon which habitually carries its tail in an upright position.
In Uganda, L’Hoest’s monkey is most likely to be seen in Kibale Forest, Bwindi or Maramagambo Forest in Queen Elizabeth National Park.
Habitat & Ecology
The species forms one-male-multi-female groups that travel long distances on the ground and forage mainly in lower forest strata.
They are omnivorous with a diet consisting of terrestrial herbaceous vegetation, invertebrates, mushrooms, fruits, flowers and small vertebrates. In areas close to cultivated land, such as the periphery of Bwindi Impenetrable and Nyungwe national parks, these monkeys enter fields and gardens to forage on crops.
These primates are found in small groups averaging 10 to 17 individuals, although larger bands of up to 37 individuals have been observed.
This species is often sympatric with Owl-faced Monkeys Cercopithecus hamlyni, especially west of the Albertine Rift. It is among the most important primate prey of leopards Panthera pardus in the Ituri Forest.
