The chimps at Gombe kill and eat as much as one-third of the Colobus population in the park each year. The others then each took parts of the carcass, sharing with other members of the troop in response to begging behaviours. Then one chimpanzee climbed up and captured and killed the monkey. Goodall watched a hunting group isolate a monkey high in a tree, block all possible exits. Jane Goodall discovered that chimps hunt and eat smaller primates such as Colobus monkeys. The biggest threats to the common chimpanzee are habitat destruction, poaching and disease. They live in the forests and savannahs of West and Central Africa. There are between 170,000 and 300,000 individuals. The common chimpanzee is listed on the IUCN Red List as an endangered species. So although it is mainly a herbivore, it does eat other animals to some extent. The species has also been seen making sharpened sticks to spear Senegal bushbabies out of small holes in trees. They use them for getting honey, termites, ants, nuts, and water. Nearly all chimpanzee populations have been seen using tools, modifying sticks, rocks, grass, and leaves. Disputes can generally be settled without the need for violence. The species lives in a male-dominated strict hierarchy. The common chimpanzee lives in groups which range from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The infant is weaned at about three years old, but usually maintains a close relationship with its mother for several more years it reaches puberty at the age of eight to 10, and its lifespan in captivity is about 50 years. The common chimpanzee is more robust than the bonobo, weighing between 40 and 65 kg (88 and 143 lb) and measuring approximately 1.3 to 1.6 m (4 ft 3 in to 5 ft 3 in) from head to tail. The common chimpanzee is often called the chimpanzee (or "chimp"), but this can refer to both species in the genus Pan: the common chimpanzee and the closely related bonobo.Įvidence from fossils and DNA sequencing show both species of chimpanzees are the closest living relatives to modern humans. The common chimpanzee ( Pan troglodytes), or robust chimpanzee, is a species of great ape. Anthropopithecus troglodytes ( Sutton, 1883).Troglodytes troglodytes (Blumenbach, 1776).
