Mbh 8.41.1b

He lived fearlessly in the dominions of a king that was guided by virtue. There was a crow that lived on the refuse of the dishes set before those well-behaved young children of the Vaishya. Those Vaishya children always gave the crow meat and curds, and milk, and sugared milk with rice, and honey, and butter. Thus fed with the refuse of their dishes by the young children of that Vaishya, the crow became arrogant and came to disregard all birds that were equal to him or even superior. It chanced that once certain swans of cheerful hearts, of great speed and capable of going everywhere at will and equal unto Garuda himself in range and speed of flight, came to that side of the ocean. The Vaishya boys, beholding those swans, addressed the crow and said, 'O ranger of the skies, thou art superior to all winged creatures.' Deceived by those children of little understanding, that oviparous creature from folly and pride, regarded their words to be true. Proud of the refuse of the children's dishes upon which he fed, the crow then, alighting in the midst of those swans capable of traversing great distances, desired to enquire as to who amongst them was their leader. The foolish crow at last challenged him amongst those birds of tireless wings whom he regarded their leader, saying, 'Let us compete in flight.' Hearing those words of the raving crow, the swans that had assembled there, those foremost of birds endued with great strength, began to laugh. The swans then, that were capable of going everywhere at will, addressed the crow, saying. 'We are swans, having our abode in the Manasa lake. We traverse the whole Earth, and amongst winged creatures we are always applauded for the length of the distances we traverse. Being, as thou art, only a crow, how canst thou, O fool, challenge a swan endued with might, capable of going everywhere at will, and doing large distances in course of his flight? Tell us, O crow, how thou shalt fly with us.
