Chimpanzee populations throughout Africa differ in tool-using behavior, a likely example of animal culture. We exposed two Ugandan groups at Budongo and Kanyawara to an unfamiliar problem, honey trapped within a fallen log. We found that individuals relied on their cultural knowledge to solve this problem. The video shows how a Kanyawara chimpanzee manufactured a stick to access the honey.

It would be nice to see this in HD, possibly with some text or narration in the vid. Keep up the good work! I'd like to see how this evolves in to. :)
