Common Chimpanzee

== Description ==
The chimpanzee (Pan troglodytes) is a species of great ape native to the forest and savannah of tropical Africa. When its close relative the bonobo was more commonly known as the Pygmy chimpanzee, this species was often called the Common chimpanzee or the Robust chimpanzee. Chimpanzees often appear in Western popular culture as stereotyped clown figures and have been featured in entertainments such as chimpanzees' tea parties, circus acts, and stage shows. Many chimpanzees have been kept as pets but their strength, aggressiveness, and unpredictability make them quite dangerous in this role.
== Appearance ==
Chimpanzees are large primates with long black hairs that cover their bodies sparely, exception for their palms, their faces, and the soles of their two feet. The parts of their bodies that are hairless are colored light to dark brown, depending on the individual's age. They have large ears and over their eyes is a heavy brow-ridge. Chimpanzees have good sight and can see in color. Their fingers are long and they have an opposable big toe. With arms longer than their legs, chimpanzees are able to get about on all fours, known as knuckle-walking. They have 32 teeth, very similar to human teeth.
== Distribution ==
Chimpanzees inhabit tropical forests in central Africa and are found from Uganda in the east to Gambia in the west, except for the area bordered by the Lualaba and Congo rivers in central Zaire (Congo). These primates inhabit a range of different areas, from tropical, humid rainforests to dryer and more arid savanna and open woodland areas.
== Lifestyle ==
Chimpanzees are very sociable animals, active during daylight hours, and spend their time feeding, grooming, and playing with the members of their group. The size of a group can range from 15 to 120, depending on the habitat and how much food is available. They are very territorial with no tolerance for outsiders, and can even kill an individual from another group. At night chimpanzees make nests in trees by bending branches to construct a safe platform where they can sleep, building a new nest each day. Although a lot of time is spent sleeping and eating up in the trees, usually they travel on the ground along a network of paths, balancing on their knuckles.
== Diet ==
The chimpanzee is omnivorous and eats a huge variety of food. The main part of their diet consists of fruits, flowers, and seeds picked from trees. They also eat insects such as termites and ants, extracted from their nests by means of a stick. They also use chewed leaves to soak up water like a sponge, drinking the water from the leaf.
== Reproduction ==
Chimpanzees have a polygynandrous (promiscuous) mating system in which males and females mate with several mates in their community. A male and female can form a consortship and mate outside their community. In addition, females sometimes leave their community and mate with males from neighboring communities. There is no clear breeding season for chimpanzees, and mating can take place at any time of the year, with babies born in any season. Gestation lasts for about 8 months and then a single infant is born. The mother and her baby remain in continual contact during their first year. At two years old, young chimpanzees are able to sit independently and move about. They are weaned at the age of 4 to 6 years. They learn survival skills by observing their mother to find out what to eat, how to build nests, and make tools. Playing with other young chimpanzees allows them to practice grooming as well as wrestling skills. Females at 13 years of age are thought to be ready to reproduce, while males reach sexual maturity at about 16 years old.
== Population ==
=== Population threats ===
The chimpanzee is on the IUCN list as being endangered in its natural habitat. Its biggest threats come from habitat destruction, disease, and poaching. The illegal exotic pet trade provides incentives to poachers to hunt chimpanzees. Adults are killed for bushmeat so that the poacher can take young chimpanzees to sell as pets.
=== Population number ===
According to IUCN Red List, as of 2003, the total Common chimpanzee population size was estimated to be 172,700–299,700 apes. Four subspecies of the Common chimpanzee have been recognized and current estimates for each subspecies are following: Nigeria-Cameroon chimpanzee - fewer than 6,000-9,000, Eastern chimpanzee - 181,000-256,000, Central chimpanzee - 140,000, Western chimpanzee - 18,000-65,000. Overall, currently, Common chimpanzees are classified as Endangered (EN) on the IUCN Red List and their numbers today are decreasing.
=== Ecological niche ===
Chimpanzees, as predators, may have a role in controlling the populations of their prey. They have a large impact on the Red colobus monkey, bush pigs, and baboons by predating them. Chimpanzees may also help with the dispersal of seeds of certain plants, through transportation, or by eating the fruit.
== Fun Facts ==
Chimpanzees are among the world's most intelligent animal species. They can remember things and recognize themselves in a mirror.
Chimpanzees exchange kisses, hugs, and affectionate touching, and use a complex system of sounds for communication.
A chimpanzee is 6-7 times stronger than a human.
To combat boredom, chimpanzees play various games.
Chimpanzees in captivity have been able to learn human sign language.
When ill, chimpanzees eat medicinal plants to cure themselves.
