![]() Not unlike gorillas, chimpanzees usually walk on all fours, otherwise known as knuckle-walking, but have been recorded to walk on two feet on the rare occasion.Ĭhimpanzee are Currently an Endangered Species Chimpanzee lifespan in the wild is a bit more difficult to record but one research has found chimps living at Ngogo in Uganda’s Kibale National Park to have an average life expectancy of 33 years.Ĭhimps get around by a lot of climbing and swinging from tree to tree. Though the average life expectancy for captive chimps are around 38 years old. ![]() The oldest recorded chimpanzee was Little Mamma, a captive female who was between 76 to 82 years old when she died in 2017. Infant chimpanzees will cling on to its mother’s furs and ride on her back until the ages three to five, resulting in a close familial bond even after reaching maturity. Most pregnancies typically carry only one child. Extended family groups can grow as large as 20-120 individuals and can have strict hierarchies, with just one dominant alpha male at the head.įemale Chimpanzees Only Give Birth Once Every Five Years They live in fission-fusion societies – meaning the size and composition changes over time – that breaks off in smaller, often interchangeable groups.

Though they have been recorded to hunt other wildlife like monkeys or small antelope for meat. A chimpanzee’s diet consists of everything from seeds, leaves, insects, honey and even roots. They are happy to eat most foods but they tend to eat more fruit than any other food groups. From using small branches to dig out termites from their mounds, to smashing rocks to crack open nuts to searching the right length of twig to scratch themselves, chimpanzees have real creativity in turning tools to their benefit. Much like humans, chimpanzees utilise self-made tools in order to feed and protect themselves, and have found ingenious ways to do so. Washoe also managed to pass on some signs to her adopted son later on.Ĭhimpanzees are one of the Few Animals that are Known to Use Tools. A chimpanzee named Washoe, was known to be the first non-human to learn to communicate via ASL and was able to do more than 350 signs. ![]() In captivity, chimpanzees have been able to pick up American Sign Language (ASL) to communicate with caretakers. The remainder of the chimps would be designated for retirement into the Federal Sanctuary System.Chimpanzees Have the Ability to Learn Human Languages such as Sign Language. In 2013, under intense pressure from organizations and the public, the National Institutes of Health announced it would retain, but not breed, a colony of up to 50 chimpanzees for potential use. The International Species Inventory System monitors the status of all the captive chimps. The Chimpanzee Management Plan (CMP) also established chimpanzee-related research bases at Yerkes and the University of Texas, as well as at Texas A&M in College Station and at the University of Pittsburgh. Under a series of grants, the plan established breeding colonies of chimps at the Yerkes Regional Primate Research Center in Atlanta, the University of Texas in Bastrop, the Primate Foundation of Arizona in Tempe, the University of Southwestern Louisiana in New Iberia, and New Mexico State University (NMSU) in Alamogordo. During the late 1980s, the National Institutes of Health (NIH) developed its so-called "National Chimpanzee Management Plan." This plan was, in reality, just a funding mechanism for five breeding colonies to maintain a steady supply of chimpanzees for vivisectors. ![]()
