Rooks show there may be some truth to Aesop’s fable ‘The Crow and the Pitcher’ LA Times Blog
The Crow and the Pitcher is a fable ascribed to Aesop, number 390 in the classification established by Perry. It is found in the 2nd century AD Greek fable collection by pseudo-Dositheus,[1] and later appears in the 4th–5th century Latin verse collection by Avianus.[2]
In the fable, a thirsty crow comes upon a pitcher with water at the bottom, beyond the reach of its beak. After failing to push over the pitcher, the crow devises a clever plan: it drops in pebbles, one by one, until the water rises to the top of the pitcher, allowing the crow to drink.
