Aesop's fables are known for teaching moral lessons rather than literally being true. But a new study says at least one such tale might really have happened.
It's the fable about a thirsty crow. The bird comes across a pitcher with the water level too low for him to reach. The crow raises the water level by dropping stones into the pitcher. (Moral: Little by little does the trick, or in other retellings, necessity is the mother of invention.)
Now, it appears the fable was rooted in fact, with birds from Cambridge University aviary quickly mastering the technique described in the 2,000-year-old tale.
The rooks, members of the crow, or corvid, family, swiftly learned that adding stones to a cylinder half-filled with water would bring the tasty worm floating on the surface within reach of their beaks.

crows are by nature very intelligent birds and easily figure out ways to achieve whatever they try to do.
