In 2003, a group of scientists and conservationists called for an upgrade in the status of chimpanzees from endangered to critically endangered. However, as human populations in Africa continue to grow, many of these reserves may be used to fill human needs. Most African nations have passed laws and have set aside areas to protect chimpanzees. Two sanctuaries exist in Gambia and Zambia for orphaned chimpanzees and those seized from illegal traders. For each chimpanzee shipped overseas, ten die during transport due to mistreatment and malnutrition. Many chimpanzees are caught and traded illegally. And the conversion of forests into agricultural land has threatened chimpanzees in Rwanda and Burundi.Ĭertain laws prohibit the hunting and sale of chimpanzees, but these laws are not enforced. The cutting of forests for timber has destroyed the animals' habitat in Uganda. ![]() ![]() Mining has destroyed the chimpanzee habitat in the diamond districts of Sierra Leone and the iron districts of Liberia. Habitat destruction, disease, and expanding human populations have led to the decline in the number of chimpanzees. The rest are zoo exhibits, entertainment props, and private pets. Over one-half of these are used as subjects in medical research. Only 10 present-day African nations have chimpanzee populations above 1,000.Ībout 5,000 chimpanzees exist in captivity worldwide. Now, estimates vary, but it is thought that there are between 200,000 and 225,000 chimpanzees in the wild, and many believe these estimates are high. They inhabited a range of ecosystems, from dense forests to open savannas. Habitat and current distributionĪ few centuries ago, several million chimpanzees existed in the equatorial regions of Africa. Bonds between mothers and infants are very strong, and some last a lifetime. During the course of her life, an average female chimpanzee will give birth to fewer than five infants. After a gestation (pregnancy) period of 230 to 240 days, a female chimpanzee gives birth to a single infant. Instead, females often mate with males of their choosing. Unlike many other animal species, female chimpanzees do not have to mate with the dominant male in their group. Mating between male and female chimpanzees takes place anytime during the year. At times, chimpanzees band together to hunt animals such as antelopes and monkeys. A chimpanzee's diet consists mainly of fruit, but they also eat insects, leaves, flowers, bark, seeds, tree resin, eggs, and meat. At night, they stay in nests they build in treetops. During the day, the animals often travel on the ground. Highly social mammals, chimpanzees live in communities made up of 30 to 60 members. The hair around a chimpanzee's face grays with age, and older chimpanzees often become bald. A chimpanzee's hair-lessįace can range in color from almost white to almost black. ![]() Most of its body is covered with long, black hair. Since its arms are longer than its legs, a chimpanzee walks on the ground using the soles of its feet and the knuckles of its hands. Researchers have documented chimpanzees making and using tools, expressing complex emotions, forming bonds and friendships, and communicating using sign language.Īn average chimpanzee stands 5 feet (1.5 meters) tall and weighs about 150 pounds (68 kilograms). ![]() In addition, the two groups share many social and psychological traits. Chimpanzees and humans share 98 percent of the same genetic makeup. Of the three, chimpanzees are the most closely related to humans. Range: Burundi, Cameroon, Central African Republic, Congo, Congo Republic, Côte d'Ivoire, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Nigeria, Rwanda, Senegal, Sierra Leone, Sudan, Tanzania, Uganda Description and biologyĬhimpanzees, gorillas, and orangutans are all considered great apes.
