Guenons

Like most monkeys, guenons are most active during the daytime. During the hottest part of the day, around noon, they rest, and groom themselves and each other. This is their only form of social contact. In the morning and late afternoon, they spend their time looking for food. While foraging, they communicate with each other through a series of peaceful calls. If a member of the troop encounters a dangerous situation, he emits a sharp barking sound, which is repeated by the troop members. On these occasions, all of the monkeys in the troop climb higher to get a better view of the danger. After doing so, the monkeys flee by running and jumping through the tree canopy. By extending their bodies vertically, guenons can leap very long distances from branch to branch.
