Because the crows were always raiding the farmer's field, he put down traps to catch them. One careless crow was caught by the foot, and stood there crying piteously.
An eagle, the king of birds, was flying overhead. "Please save me," called the crow, "and I'll catch five mice and bring them to you." So the eagle pulled the trap apart with its strong beak, the crow escaped. But once he was free, it forgot all about its promise.
One day, it was caught in another of the farmer's traps. Again, he cried for help, but this time the eagle flew on saying "Don't expect me to save you a second time when you couldn't keep your first promise."
