Chimpanzees spend a lot of time grooming injuries on themselves and others. In fact, we rely heavily on observation of their behavior towards one another to monitor their health. For example, a chimpanzee may develop a small abscess from a bite or scratch during a fight. Depending on the location of the injury, the caregivers may not notice it at first. But the chimpanzees sure do, and this will often alert us to its presence. And while we tend to be a bit overly cautious and provide oral antibiotics, the chimpanzees do a pretty good job of grooming and draining injuries to promote healing on their own. This makes sense, of course, because free-living chimpanzees often suffer injuries and do not rely on humans for treatment. But it is fascinating to watch. Missy seems to be the most adept at using tools (in this case a piece of grape vine) to groom herself.
