The Conte Crow

The common crow is more than smart; ravens and crows in the past have shown the ability to communicate with people answering vocally by mimicking language or by other means, tapping with their beaks a number of times meaning one answer or another.

Crows have been seen dropping nuts on busy roads letting cars break them open and then retrieving the nut from the road when the coast is clear.

Also some are known for using bread crumbs (that they would normally eat) to lure fish to the surface of the water and then catching the fish itself proving a much larger meal then a bread crumb.
