There was an old banyan tree in a forest. A crow-couple had made their nest in the tree. There was a hollow in the lower part of the trunk of the tree. A snake had come from somewhere and made it its home.
After a few days, the mother crow laid eggs. In due course of time, chicks hatched out of the eggs.
One day the parent-crows left their nest in the morning in search of food. In their absence, the snake entered their nest and devoured the little chicks.
When the parent-crows returned, they felt very grieved to see their nest empty. They asked the other birds living in the tree about their chicks but none could tell them anything. They bewailed helplessly and at last fell silent.
After some time, the mother-crow again laid eggs and little chicks hatched out them. The couple decided not to leave the chicks alone. One day the mother-crow was sleeping in the nest. The crow was away looking for food and the chicks were playing. The wicked snake crawled silently towards the nest.
When the chicks saw the snake, they raised a hue and cry. Their noise disturbed their mother's sleep and she woke up. Seeing the cruel snake advancing towards the chicks, she raised an alarm----"caw…caw…caw…."
Suddenly a kite appeared on the scene. Seeing his enemy just at hand, the snake crawled back into his hollow quickly.
In the evening, when the crow returned the mother-crow told him all that had happened. He felt shocked. Then the mother-crow said, "It is not safe to live here now. Let us make our nest in some other tree far away."
"Don’t say that. Have you ever heard of anybody leaving his or her home out of fear?" retorted the crow.
"How will we save our chicks from the cruel snake then?" asked the mother-crow.
The crow was worried but he said, "Let me go to Miss Fox who lives just near by. I am sure she will suggest a way out."
The crow narrated the tale of woe to the fox. Thinking over the problem, the fox said, "You need not leave your home. I have a plan to get the snake killed."
The fox said, "Tomorrow morning, the prince of a nearby kingdom will come to the river for a bath with his servants and body-guards. He will take off his clothes and crown before going into the water. You must be present there before hand. Dodging the guards, pick up the crown of the prince and fly slowly to the snake's hollow. The royal bodyguards will follow you to the end. Throw the crown into the hollow in their presence. They will dig the hollow and kill the snake."       
The crow liked the plan and decided to act upon it. Returning home, he told the mother-crow about it. Next day the crow went to the riverbank. After some time, the prince arrived, took off his clothes and crown and dived into the water.
The crow was already waiting. He at once pounced on the crown and picking it in his beak, flew away slowly. Seeing the crow take away his crown, the prince shouted, "Look! The crow has taken my crown. Catch him, catch him." The bodyguards ran after the crow. Flying slowly to the snake's hollow, the crow threw the crown into it as planned. The bodyguards started digging the hollow. At this, the snake came out and stood before them hissing angrily.
The bodyguards killed the snake there and then. Taking the crown out of the hollow, they returned to the prince. The crow-couple felt overjoyed to see their enemy killed. They went to Miss Fox and thanked her.
