Chimpanzees are found in dense rain forests, open woodlands, and broad grasslands of Africa.The number of chimpanzees in the wild has been reduced to about 200,000, scattered across 21 nations in Africa.
The scientific name for the chimpanzee is Pan troglodytes. Chimpanzees are apes, like orangutans, bonobos, gorillas, and gibbons. Apes belong to the primate order that includes lemurs, monkeys, and humans.
On the ground, chimpanzees travel on all fours when walking. During the day chimpanzees spend most of their time in trees, sometimes swinging from branch to branch. They travel mostly on the ground. They use a technique called knuckle-walking—their weight is supported on the soles of their feet and the back joints of their fingers. Chimpanzees live in social groups called communities or unit groups that consist of up to 60 members. Each chimpanzee has its own individual pant-hoot, a common call used in different situations.Chimpanzees travel in small bands of up to six animals, though the membership of the travel groups changes as individuals separate or join other groups.
Chimpanzees use various sounds and gestures to communicate with other chimps.
Grooming is an important behavior for chimps, both socially and for skin care.
Grooming helps chimpanzees maintain friendly ties with community members. A grooming session can continue for a few seconds or hours and include several chimpanzees of different ages.
In the wild female chimpanzees give birth every five or six years.
Chimpanzees forage for food about six to eight hours a day. Chimpanzees can live about 50 years in the wild. In captivity, some chimps have lived more than 60 years.
The main threats to chimpanzees are the loss of habitat from agriculture and logging, and hunting by people for food. Male chimpanzees try to intimidate other males with displays of dominance: slapping their hands, stamping their feet, dragging branches, and throwing rocks.
