This 2015 video from Africa says about itself:
This amazing video documents the story of Wounda, one of the more than 160 chimpanzees living at the Jane Goodall Institute’s Tchimpounga Chimpanzee Rehabilitation Center in the Republic of Congo.
Thanks to the expert care provided at Tchimpounga, Wounda overcame significant adversity and illness and was recently relocated to Tchindzoulou Island, one of three islands that are part of the newly expanded sanctuary. Dr. Jane Goodall was on hand to witness Wounda’s emotional release, and now you can too.
Disclaimer: Please note, that Dr. Goodall and the Jane Goodall Institute do not endorse handling or interfering with wild chimpanzees.
Termite fishing by chimpanzees was thought to occur in only two forms with one or multiple tools, from either above-ground or underground termite nests. By carefully observing the techniques required to termite fish at ten different sites, researchers have created a catalog of behaviors for each chimpanzee in the study: here.
Researchers have systematically investigated developmental milestones in wild chimpanzees of the Taï National Park (Ivory Coast) and found that they develop slowly, requiring more than five years to reach key motor, communication and social milestones. This timeframe is similar to humans, suggesting slow maturation of the brain: here.
