Bald Uakari

The bald uakari (Cacajao calvus), also known as the red uakari or bald-headed uakari, is a distinctive red-faced monkey found in swampy forests. It is in Brazil, Peru, and Colombia. The species is considered “near threatened” by the 2004 World Conservation Union (IUCN) Red List. This was because of hunting and the destruction of its habitat.

They have little fur on the face, with bright red facial skin a sign of good health. This enables them to choose the healthiest (most red-faced) to mate with. They have long, thick, white or red body fur with short, bushy tails. They are on average 21.65 inches (55 cm) long and weigh around 6.61 pounds (3,000 g). They usually live around 20 years.

Bald uakaris feed mainly on seeds and flowers, and some small animals.

They live in mixed groups of between five and 30 members. They spend most of their time on the ground searching for seeds, and at night sleeping in trees for safety. The breeding season is between October and May. The female encourages the male to mate by releasing an attractive scent. The gestation period is unknown.
