Scientists investigate why crows are so playful Video Description

The real question is whether there's a direct relationship between playing with something and then using it as a tool. The first two experiments that the researchers designed were attempts to answer this question. Researchers tested six wild New Caledonian crows, who had been caught five weeks before the study. For comparison, they also tested eight kea, born in captivity. Kea are known for their playful exploration of objects, but they don't use tools in the wild.
