Some adult females become bald. Their feet have five toes, including an opposable big toe. Chimpanzees can grasp things with both their hands and their feet. SIZE Male chimpanzees are larger than the females. They forage for food in the forests during the day, eating leaves, fruit, seeds, tree bark, plant bulbs, tender plant shoots, and flowers.
Chimpanzees drink water, often by using a chewed leaf as a sponge to sop up the water.
Chimpanzees often use tools in the wild. They have been observed using sticks to obtain ants and termites to eat and to scare away intruders. They also use chewed-up leaves like a sponge to sop up water to drink. Smaller subgroups of 6-7 chimps stay together for a while, with the membership changing over time. These bowl-shaped nests are made out of leaves and other plant material.
