New Caledonian Crow and The Use of Tools
Lecturer: I’m going to talk today about research into a particular species of bird, the new Caledonian crow, whose natural habitat is small islands in the Pacific Ocean. And it seems that these crows are exceptionally resourceful. Using sticks or other tools to find food isn’t unknown among birds and animals. Some chimpanzees, for example, are known to bang nuts on stones in order to break the shell and get the edible kernel inside. One new Caledonian crow called Betty spent some straight wire into a Q31 hook and used it to lift a small bucket of her favorite food from a vertical pipe. This experiment was the first time she’d been presented with wire, which makes it very impressive.
