Once the Bodhisatta was a parrot named Rádha and his brother was Potthapáda. They were captured by a fowler and brought to the court of Dhanañjaya, king of Benares, where they were paid great attention. Later, a monkey, Kálabáhu, was added to the collection of animals, and the people in the palace lost interest in the parrots, much to the annoyance of Potthapáda. Soon, however, the children became frightened of the monkey's tricks and he was sent away, just as Rádha had prophesied to his brother.
Ananda was Potthapáda, and Devadatta, Kálabáhu.
The story was told in reference to Devadatta's attempt to kill the Buddha by letting loose Nálágiri. J.iii.97ff
