The Proud Peacock: A Story About Humility (Jataka Tales)

A golden mallard, chosen by the birds to be their king, grants his daughter's wish to select her own mate. From all available candidates, the princess chooses an elegant peacock. Delighted, the peacock shows off his beauty. Realizing his prideful nature, the mallard princess rejects the peacock and chooses a more modest mate. Deeply ashamed, the peacock utters a hoarse cry of dismay. To this day, peacocks still make this same sound.
