The crested mona monkey, also known as the crowned guenon, crowned monkey, golden-bellied guenon, or golden-bellied monkey, (Cercopithecus pogonias), is a species of African primate in the family Cercopithecidae found in west central Africa.
The crested mona monkey is a medium-sized, long tailed arboreal monkey. The females are smaller than the males but show similar colouration and pattern of coat. They have a brown coat speckled with grey which becomes black on its lower arms and legs and on the base of its long tail. The rump, belly and the insides of the legs are golden-yellow contrasting with the rest of the fur. The males have a distinctive blue scrotum. Their faces are mainly dark blue with a pink muzzle. Around the face the fur is yellow marked with a wide black stripes which runs from the beside the eyes over to the temples and across the centre of the forehead where it forms the characteristic small crest which gives this species its common name.

GBIF citizen-science records
It is estimated from how often the Crowned Monkey is recorded against all the mammals logged in Odzala-Kokoua National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
