Chimps Using Tools

I've captured them using sticks before to fish for food, but this is the first time I've seen the leaf sponge demonstrated. Jeff chews the leaf then dips it in the water. In the wild chimps do this to access hidden stores of water, deep in tree crevices for instance. In Jeff's case he found an added use which was to drip water over poor Sally's back. #chimp #apes #greatapes #chesterzoo #primates #primatesarenotpets #chimpanzee #chimpbehaviour
