Chiropotes utahicki occurs south of the Amazon between the Xingu and Tocantins rivers in Brazil. Its beard-like facial fur and bushy tail stand out; a studied group ate mainly seeds and fruit.
Bearded sakis have a thick beard and paired crown tufts. Longer fur on the shoulders and upper arms can form a cape-like outline; the adult tail is bushy but not prehensile.
A group observed on an artificial island in Pará moved rapidly through the upper forest strata and sometimes split into small subgroups. Seeds and fruit were the main foods; leaves and cambium were also recorded.
