L’Hoest’s Monkey or Mountain Monkey, is a guenon found in the upper eastern Congo basin. They mostly live in mountainous forest areas in small, female-dominated groups. They have a dark coat and can be distinguished by a characteristic white beard.
L’Hoest’s Monkey occurs in northeastern Democratic Republic of the Congo, Rwanda, Burundi, and western Uganda. It is a forest monkey, which is typical of the moist and high primary forests. It will occupy a range of different kinds of forested areas, including gallery forest, mature lowland rain forests, wooded savanna at mountain slopes, and forest borders. However, it also will live on cultivated lands. In lowland forests it shows a preference toward areas where the forest is regenerating, while in mountain areas it will frequent the mature, tangled, undergrowth below the broken canopy.
They make their homes in remarkable nests in trees.In the wild they are primarily an herbivore, which will mostly eat fruit, mushrooms, herbs,roots, and leaves. However, it will also occasionally eat eggs, lizards, and small birds.
