Biologists have observed astonishing tool-manufacture behaviour in wild New Caledonian crows, which may mean that textbooks on animal intelligence will have to be rewritten.

In 2002, ‘Betty’ the New Caledonian crow astonished the world when she deftly bent wire into a hook to obtain food - widely regarded as one of the most compelling demonstrations of ‘intelligent’ behaviour in a non-human animal.

However, recent field experiments funded by BBSRC and conducted by a team of biologists at the University of St. Andrews have now revealed that tool bending is part of New Caledonian crows’ natural behavioural repertoire, casting doubt on Betty’s problem-solving prowess. But the researchers say a curved tool might be advantageous, because the bird can position it in its bill so that the tool-tip is bang in the middle of the field of binocular vision.
