Species: Cacajao calvus rubicundus
Common Name: Bald Uakaris
There are three subspecies of Cacajao calvus; Cacajao calvus rubicundus, Cacajao calvus ucayali, and Cacajao calvus calvus. Not much is known about either subspecies. In this post I focus on Cacajao calvus rubicundus, or the red uakari.

The red uakari lives along the Brazil-Columbia in seasonally flooded or permanently flooded forests. The prefer to live alongside small rivers or lakes and spend most of their time high in the canopy. The are larger in size than the Saki and are the only short tailed platyrrhine. The are diurnal and eat fruit, leaves, nectar, insects, and seeds (mainly during the dry season when the can descend to the forest floor). They travel in groups of 10-30 individuals, although groups with as high as 50 have been reported.
