Clever cockatoos bend hooks into straight wire to fish for food

In the early 2000s the New Caledonian crow Betty in Oxford shocked the world when she spontaneously bent a hook into a straight piece of wire while trying to retrieve a small out-off-reach basket with a handle from a vertical tube. Interestingly, when human children were tested on a similar task setup they showed great difficulties with coming up with a suitable solution until the age of nearly eight years. New Caledonian crows are specialized tools users in the wild and their ability to handle tools is innate. Nevertheless, in this case Betty seemed to innovatively produce a novel behavioural sequence on an unknown material.
