Chimpanzee

Chimpanzees primarily eat fruit, but will also consume other plant material, as well as insects and will even hunt smaller monkeys. The species lives in groups which can number over 200 members, although individuals travel and forage in much smaller groups during the day. They live in a strict male-dominated hierarchy, where disputes are generally settled without the need for violence. They will sometimes attack other groups for control of resources and mates. Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass and leaves and using them for hunting and acquiring honey, termites, ants, nuts and water. Gestation in the species lasts eight months. The infant is weaned at about three years old but usually maintains a close relationship with its mother for several years more. Chimpanzees communicate with a variety of vocalisations, facial expressions, gestures and body postures.
