Rook uses stones to raise water level and get food 4

Cook selectively drops stones into the tube containing water rather than the tube containing sawdust. Cook flies to the testing platform and investigates both tubes before the stones are added. Cook adds four large stones to the water before successfully acquiring the worm. He then leaves the testing platform.

Its fascinating to see how this rook works out that the stones will raise the water level.  What a clever rook! Actually, this item was on BBC News this morning - 7.08.09. :-)
