The White-throated Guenon, also called the Red-bellied Monkey, is native to rainforest of Nigeria and Benin.
There are two subspecies. Shown is the nominal which is also the Red-bellied. The other is the Nigerian White-throated.
This rare and highly endangered monkey was thought extinct, driven to extinction by hunting for its prized red belly fur
and white fur. Some were re-discovered in 1988.
In addition to the white throat/beard, they have blond highlights on the head.
They live in groups of a dominant male and several females. Bachelor males are mainly solitary.
