White Bald-headed Uakari

Cacajao calvus

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The bald uakari is an unmistakable Amazonian monkey: a bare face of intense red, a bald head and long fur that may be white, golden or reddish according to the subspecies. It lives in the seasonally flooded forests of the western Amazon, moving through the canopy in groups that can exceed a hundred animals. It feeds mainly on the hard seeds of unripe fruit, which it opens with prominent incisors and powerful jaws, a niche that almost no other primate exploits.

Fun facts

  • The red of its face is a health indicator: individuals with malaria or parasites turn pale, while healthy ones show an intense red, and females prefer the more highly coloured males.
  • It has the shortest tail of any American monkey, barely a third of its body length, an unusual feature among the fauna of the Amazon canopy.
