The Cincinnati Zoo is the only institution in the world that exhibits this species.

Living in social groups led by a single male, Grey's crowned guenons (Cercopithecus pogonias grayi) rely on their colorful coats and vocalizations to communicate with each other. Specially adapted for life in the trees, guenons rarely come down to the ground.
