white uakari

The white uakari, also known as the bald uakari, is a type of short-tailed South American monkey belonging to the genus Cacajao. These monkeys are characterized by their shaggy fur, humanlike ears, and distinctive bald faces that turn red when they are excited.12

Uakaris are diurnal, living in groups of about 15 individuals and primarily feeding on fruit. They are agile climbers, leaping between trees with their arms outstretched. There are two species and three color forms of uakaris, all of which are either endangered or vulnerable. The white uakari (C. calvus calvus) has whitish fur and a bright red face, leading to its nickname "English monkey" among locals. It inhabits flooded forests along the upper Amazon River in Brazil. Uakaris are one of the few New World monkeys without a prehensile tail.1
