Red-eared guenon
The red-eared guenon natural habitat is subtropical or tropical moist lowland forests. It is found in primary and secondary lowland tropical and sub-montane moist forest, and sometimes lives in close proximity to humans, as on Bioko.
The red-eared guenon is threatened by deforestation and by the bushmeat trade, particularly on Bioko, where it is frequently recorded in bushmeat market in Malabo. Hence it is threatened by habitat loss due to deforestation, illegal bushmeat hunting and pet trade. It is endangered.
