Kuntani Jātaka
Kuntani Jātaka:In the court of the king of Benares was a heron who carried messages.Once,when she was away,the boys of the palace killed her two young ones.In revenge she persuaded a tiger to eat the boys,and told the king what she had done.She then flew away to the Himālaya because,she said,there could be no friendship between the wrong-doer and the wronged one.
The story was told in reference to a heron of the Kosala king,who acted in a similar way (J.iii.311f).
