The Amazing Crow

Aesop's fable? This one turns out to be true - Science, News - The Independent
update: Here is the video

One of Aesop's fables describing a thirsty crow which was able to drink from a half-full pitcher after raising the water level by adding pebbles may have had a basis in real life.

Scientists have found that rooks – a member of the crow family – were able to figure out how to raise the water level in a laboratory container by dropping stones inside to retrieve a tasty worm floating on the surface.

Four different rooks, called Cook, Fry, Connelly and Monroe, quickly discovered that they could raise the water level in a transparent container by adding stones, just like the mythical crow in the fable, which illustrates the virtue of ingenuity and how necessity is the mother of invention.
