Uakari (wəˈkɑːri/) is the common name for the New World monkeys of the genus Cacajao. Both the English and scientific names are believed to have originated from indigenous languages.
Uakaris are typically lethargic and silent in zoo conditions, but in the wild they are agile and active, capable of leaps of over 6 meters. They have been observed both in small groups and in larger troops of up to 100. When traveling through the forest, they move in the lower branches of the trees, though when foraging they also go up to the canopy. They eat fruit, nuts, buds and leaves.
Uakari are found in neotropical Amazon flooded or riparian forests, including Brazil, Colombia, Peru and Venezuela.
