pith and insects. They have large canines that allow them to feed on seeds from fruits with hard shells and incisors that are able to shatter the husk for access to the inner seeds. They are also known to consume fruits from many different species of trees. Overall, there is little competition with other primates for food, as most living in the same habitat do not devour hard fruits, however some competition with birds exist. Leaves are also consumed, especially when fruits are low during the dry season. Another dietary form observed is insectivory, peaking when fruit availability is low, through the consumption of fruit infested with insects or through the deliberate hunting of insects for protein. Uakaris have been seen raiding wasp nests for larvae and even eating the eggs of river turtles. Behavior They typically live in groups of 5-40 individuals, but occasionally more than 100 may come together. Individuals within a subgroup exist in close proximity and interact frequently. The uakari are diurnal. They move around by walking and running on all fours and even climbing and galloping. Leaping is the main method of travel, allowing them to cover a distance of 10 meters in one leap. Swimming is done only when required, as when they accidentally fall into the water. Newborn infants range from 25% to 67% of the mother's body length. After birth, the infants follow the mother for a year and a half, being carried on her back or front side.
