Cacajao calvus - The bald uakari and two other species of the Cebidae family are three of the few short-tailed monkeys in the Americans. These species lack facial hair and when excited, the face, already red from lack of skin pigment, becomes flushed in bright scarlet. A typical uakari group consists of 10 to 30 members passing the day feeding on nuts and fruits found in the higher canopies of the forest. The uakari is confined to a small area in South America. Habitat loss and human encroachment has placed the uakari on the endangered list.
