Crow Makes Wire Hook to Get Food

In their Science article, the researchers point out that Betty's accomplishment—purposefully modifying objects into tools without prior experience—is almost unknown in the animal world. The article cites an experiment in which chimpanzees failed to straighten a length of piping, and pass it through a hole to retrieve an apple, until they were coached.

For Kacelnik, Betty's use of creative problem-solving based on past experience may be evidence of inferential reasoning. Some scientists, he said, believe that even apes lack this capability.

"We do not yet know how far Betty and her fellow New Caledonian crows go in this direction, but this particular case is tantalizing," said Kacelnik. "We are very curious to learn the extent and nature of the cognitive adaptations that allow this. It may turn out that these crows are also better than other species of related organisms at solving tasks not involving tools. We are working on it."
