Common woolly monkeys are omnivorous, but mainly frugivorous. Their diet consists primarily of fruits containing 1 or 2 large seeds and fruits that are lower in fat and higher in sugar and water. Although they prefer certain fruits such as fruits from the Fabaceae (Legume), Moraceae (fig), Convolvulaceae, and Sapotaceae families, which represent roughly 50% of consumption time, fruit abundance and production influence their diet more than preference. As such, during periods of scarcity, fruit consumption tends to decrease and leaf and insect consumption increases. Females with dependents tend to eat more leaves, most likely because the leaves contain more protein, which helps the female produce more milk, whereas juvenile woolly monkeys have been observed to eat more arthropods than other members of the group. Foraging behavior The common woolly monkey exhibits generalist and opportunistic foraging behavior, spending a large amount of time eating and moving in the pursuit of food, covering roughly 2 km per day. They tend to prefer fruit species with a clumped fruit distribution and fruits produced by large trees because these tend to produce a larger crop size and reduce the energy spent traveling between fruit patches. Females with offspring were observed to be more efficient foragers than juveniles and adult males. Inter-group competition during feeding times causes the juveniles to be displaced by the adult males and females with offspring resulting in an increase in feeding on arthropods and leaves. Habitat and groups They are found in the rainforest, usually in the canopy of the tallest trees, though they may also be found at shrub layer. In certain seasons it is also common for groups to enter flooded forests, due to a higher concentration of berries. Social behavior Inter-group interactions Females drive the relationships that develop between opposite sexes within communities. They do not mingle with other females, whereas males will engage with either sex. Females are possessive of males and may harass others that try to interact with a male. Although they are dominant within their group, females are accepting to outsiders of both genders if there are no offspring-producing females present. Movement and seed dispersal Woolly monkeys have been observed using all four legs when walking/running and climbing, and efficiently making use of intermediate branches rather than just terminal branches when climbing. They act as more effective seed dispersers than the morphologically spider monkey due to longer seed retention time in the
