Are these guys idiots?

The research by Shoei Sugita, professor of animal morphology at Utsunomiya University, and others has confirmed for the first time in the world crows can distinguish quantities of items, suggesting the birds have the same numerical cognition ability as human beings.

Yes crows can tell which symbol means food, but does that mean they can count?
