Meat eating and ant dipping by wild chimpanzees in Sierra Leone

This report presents the first records of meat-eating and ant dipping by wild chimpanzees,Pan troglodytes, from Sierra Leone. The study was conducted in the proposed Outamba-Kilimi National Park, Northern Sierra Leone. Measurements of tools used to dip for driver ants, are compared with those from four other study sites in Africa. The results reveal some fundamentally common characteristics. From both faecal analysis and direct observation, evidence was found that the chimpanzees eat meat. These recordings indicate a varied choice of prey and add new species to those preyed upon by wild chimpanzees. These findings preliminarily support the idea that despite a wide geographical distribution throughout Africa, chimpanzees share some essential conventional behavioural patterns.
