The Bodhisatta was once a tree-sprite in a jambu-grove and saw how a crow, flattered by the words of a jackal sitting under the tree, dropped fruits for him to eat, praising his breeding. The sprite drove them both away as being liars.
The story was related in reference to a report that Devadatta and Kokālika were going about singing each other's praises. J.ii.438f; cp. Anta Jātaka.
