Science magazine has a fascintating video clip of a crow making a tool to retrieve a bucket of food.
Science excerpt: “Though these crows are known to employ tools in the wild using natural materials, this captive bird had no prior training with the use of pliant materials such as wire — a fact that makes its apparently spontaneous, highly specific problem-solving all the more interesting, and raises intriguing questions about the evolutionary preconditions for complex cognition. The crow’s behavior was captured on an unusual video clip.”
Hopefully, these kinds of experiments will go a long way toward re-educating the world on animal intelligence.
