4/2/2023 0 Comments The third chimpanzee![]() ![]() Males spend all of their lives in the community they are born in, but occasionally a juvenile male may transfer to another community with his mother. On the other hand, gang attack by subordinate males can expel an alpha male. The dominant (alpha) male of a group can monopolize ovulating females through possessive behaviour. The dominance hierarchy among male chimpanzees is very fluid individuals associate with each other and join and leave different subgroups with complete freedom. Communities usually divide into subgroups called parties, which vary widely in size. Within a community, there are twice or three times as many adult females as adult males the number of adults is about equal to the number of immature individuals. Social dominance exists, with adult males being dominant over adult females and adolescent males. Each consists of several subgroups of varying size and unstable composition. A community can number from 20 or fewer to well over 100 members. Home ranges of forest-dwelling communities can be as small as a few square kilometres, but home ranges covering hundreds of square kilometres are known among savanna communities. They are highly social and live in loose and flexible groups known as communities, or unit groups, that are based on associations between adult males within a home range, or territory. Conservation statusĬhimpanzees are lively animals with more extraverted dispositions than either gorillas or orangutans. For example, Cheetah the chimpanzee, an animal actor from the Tarzan movies of the 1930s and ’40s, was reported to have lived approximately 80 years. The longevity of chimps is about 45 years in the wild and 58 in captivity however, older individuals have been documented. Males are considered adults at 16 years of age, and females usually begin to reproduce at about 13 years, but often only two offspring survive during her lifetime. From about 6 months to 2 years, the youngster rides on the mother’s back. The newborn weighs about 1.8 kg (about 4 pounds), is almost helpless, and clings to the fur of the mother’s belly as she moves. The female chimpanzee bears a single young at any time of year after a gestation period of about eight months. They also appear to use certain plants medicinally to cure diseases and expel intestinal parasites. Chimpanzees also hunt, both alone and in groups, stalking and killing various mammals such as monkeys, duikers, bushbucks, and wild pigs. The chimpanzee diet is primarily vegetarian and consists of more than 300 different items, mostly fruits, berries, leaves, blossoms, and seeds but also bird eggs and chicks, many insects, and occasionally carrion. Chimpanzees are unable to swim, but they will wade in water. At night they usually sleep in the trees in nests they build of branches and leaves. Though able to walk upright, chimpanzees more often move about on all fours, leaning forward on the knuckles of their hands (knuckle walking). Movement over any significant distance usually takes place on the ground. They also leap and swing by their arms ( brachiate) skillfully from branch to branch. In the trees, where most feeding takes place, chimps use their hands and feet to move about. After a lengthy midday rest, late afternoon is usually the most intensive feeding period.
