The Hawk, the Kite and the Pigeons (Greek Folk Tale)

The Pigeons in a certain dovecote were persecuted by a Kite, who every now and then swooped down and carried off one of their number. So they invited a Hawk into the dovecote to defend them against their enemy. But they soon repented of their folly: for the Hawk killed more of them in a day than the Kite had done in a year.
