What they eat

The Bald Uakari eats fruits, seeds and leaves while sitting atop of trees. Sometimes, they catch insects and small animals.

What they are like

There are three species of Bald Uakari, distinguished by where they live. Each has evolved in their own way, taking on different color hair.

Monkeys with rich facial expressions
The Bald Uakari is a monkey that lives in the forest upstream of the Amazon River. Their face leaves a lasting impression, perhaps because it has no facial hair. This leaves their red skinned face exposed and which, at times, may resemble a human baby or even an old man. This may explain why they can express their emotions just as good as people can. Even better than other monkeys can, including anger and joy.

People have captured them, and now their forests are gone...
Hunting and deforestation threaten the Bald Uakari. At the turn of the 20th century, the people that came to the forests in search of natural rubber captured the Bald Uakari for food. They also captured them as pets because of their friendliness. Now, they are on the brink of extinction because forests were cut down one after the other to make farmlands and pastures. While preservation areas have been made, their population continues to decline. It looks like the only face the talented Bald Uakari can make these days is a very sad one.
