Red-tailed guenons mainly feed on fruit, but they also eat leaves and animal prey. It is common for adults to store fruit in their large cheek pouches in order to take their meal to an area free from the threat of theft by other monkeys.

These monkeys live in groups of 7-35, typically with one male and numerous females. The females remain in the same territory for life, but males tend to migrate. It is common for the incumbent male to kill all existing offspring in the new group, thereby making lactating females come into estrous sooner and bear his offspring.  They are diurnal and arboreal and travel quadruped through the forest.
