For the behavior of the chimpanzees, its very high intelligence is formative. They have a very high ability to learn. This is quickly exchanged through communication to the hordes, so that new and successful behaviors can quickly establish themselves. The use of tools to achieve goals is a matter of course for them. They also learn by watching. For example, opening a lock with a key in the zoo is hardly a challenge for them. If tools become unusable, they try to improve or repair them. They also assign value to items and learn simple language patterns. If they get pencils or brushes in captivity, they paint immediately, but never exceed a certain level of difficulty which roughly corresponds to a small child. To sleep, chimpanzees retreat into trees where they build small nests.

Contrary to earlier assumptions, chimpanzees are not monkeys of trees. Although they can climb and shimmy very well, they also build their nests in the trees, but most of the time they spend on the ground.

Depending on the amount of food they eat, they can stay on the ground or in the trees. In contrast to gorillas, chimpanzees never dirty their nests. To the Koten or urination, they usually look for elevated places or sit on fallen trees.

They live together in loose communities with a solid hierarchy. One can recognize the ranking-higher group-members well at the Zurschaustellung of its forces (Imponiergehabe). A declining of the body-forces doesn't lead automatically to the Entthronung with chimpanzees. Rather, the experience plays a big role. The mothers educate their children in groups and leave also other mothers their children occasionally on that occasion. The bandages of 40 to 60 individuals move around in smaller groups. The composition of the small groups changes constantly.

They often use gestures or postures to communicate with each other. When begging, for example, they hold their hollow hand forward.
