The unique bald uakari, red-faced rainforest resident

The Bolt Wakari monkey is known for its bright red face, a sign of good health, and its short tail and long coat. These arboreal primates live in the treetops due to forest flooding during the rainy season and descend to the ground in the dry season to forage for seeds. Native to the western Amazon of Brazil and Peru, they are considered vulnerable due to hunting and habitat destruction. Female wakaris reproduce slowly, giving birth to one infant every two years, which limits population growth.
