007,The Problem-Solving Crow

007, a very bright crow solves 8 complex puzzles in perfect order:

The crow surveys the puzzles.
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.
