Men are not the only animals capable of creating instruments: and this record was not beaten by an monkey or an elephant. During a research conducted by researchers at the University of Oxford (England), a New Caledonian crow (Corvus moneduloides) managed to build a perfect tool for the purpose it had set itself. Betty, the specimen in question, is a young two-year-old female who had to get a bucket of food out of a tube.
He had at his disposal a straight wire and a hooked wire, which was immediately stolen by an older male in the cage. Since he could not lift the bucket with the straight wire, he stopped one end of the wire and bent the rest until it formed a hook. And he repeated the test, nine times out of ten with complete success: Betty's companies are documented on this page of the University of Oxford website. The male, on the other hand, has not even tried to tackle the problem, but this does not seem to be attributable to sex.Betty's business in Oxford. |
Even if these crows, in particular, are known as users of tools, an animal (even among chimpanzees) had never been seen to build the first tool, and without any training, the right tool to solve a problem.
