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.
He had shown 007 the puzzles individually before. This, however, is the first time the crow will see them arranged in this order and he needs to figure out in which order to solve them to be successful.
The BBC showed the crow surveying the puzzles and then getting to work. He jumps up and unties the short stick from the rope. He tries the short stick to reach the treat but realizes he needs a longer one. He then uses the short stick to pull out three individual rocks from three individual cages.
When he looks like he’s stumped over what to do with the rocks, he figures it out and uses the rocks as weights to retrieve the longer stick needed to score the snack.
