Two geese from Cittakūṭa once used a certain tree as a perch, whenever they approached it, and became friendly with the spirit of the tree, who was the Bodhisatta. They talked together about religion until a jackal came and interrupted them. Then the geese flew away and did not return.
The story was told of an old monk who interrupted a conversation between Sāriputta and Moggallāna. The monk was the jackal. J.ii.106 f.
