It's a good job they don't have hands or they'd swiftly become our overlords - crows are frighteningly clever.

Dr. Alex Taylor has been studying wild birds which he keeps three months at a time.
This particular crow, called 007, had been shown each of the puzzles individually but this was the first time it had had to solve all eight in order.
