Mockingbird to Annoying Human: "Hey, I Know You"

If you get on a mockingbird's enemy list, expect to be dive-bombed every time you come within the bird's sight. That's one lesson that can be taken from a new study which proved that mockingbirds can recognize individual people, and attack those who have bothered their nests in the past. While ornithologists knew that certain highly intelligent birds like parrots and crows can recognize humans in a lab setting, they were surprised to find similar behavior in a songbird living in the wild.
