Last month, scientists in New Zealand published a study showing that crows can solve puzzles to get food. They offered crows food that was floating on top of water in tubes. The problem: the tubes were narrow, so only their beak fit in. And the water level was so low the crows couldn’t reach the food. Fortunately, the scientists provided the crows with an assortment of blocks and other heavy items. The crows figured out that if they dropped the blocks in the tube they would displace the water, raising the food to a level where they could reach in and grab it with their beaks.
