The Red-eared guenon is classified by IUCN as vulnerable. Cercopithecus erythrotis camerounensis is found only in southeast Nigeria and southwest Cameroon (known as the Cameroon faunal region), and Cercopithecus erythrotis erythrotis on the island of Bioko. Red-eared guenons share their habitat in this small geographic area with many other endangered mammals, including the rare subspecies of lowland gorilla, the Cross River gorilla (Gorilla gorilla diehli) and the drill monkey (Mandrillus leucophaeus).
Amongst the smaller of the forest guenons, Red-eared guenons are also very quiet in the forest, with their soft trill-like contact call. In addition to their bright brick red nose, they also have tufts of red hair on their ears and long brick red tails. They are a close cousin to the Sclater’s Guenon, and formerly Sclater’s guenon was considered a sub-species of C. erythrotis. Little is known about their ecology and behaviour. They are frequently found in mixed species groups with putty nose guenons. In CERCOPAN’s Rhoko Core Area, there is a resident group of Red-eared guenons who are often observed with the resident Putty-nosed guenons.
CERCOPAN’s Red-eared guenons are amongst very few captives known anywhere in the world. We rarely see this species as captive pets – their survival rate in comparison to other guenons is very poor. Their quiet nature also makes them more difficult to hunt, and their small size means, fortunately, they are not as popular for bush meat.
