When birds are allowed only one call and color, who will remind us of the joy to be found in a variety of songs and plumages?

One day, above an oak, a dark raven circles, offering berries in exchange for loyalty. Drawn by the juicy fruit, many birds join and obey him. Soon, he claims that black feathers alone are beautiful and "Caw" is the only proper call. His followers, the Caw-Caws, tar other birds's feathers and gag the beaks of all those who won’t sing along. But the next week, another crow appears and cries: "Hoo? Hoo? Have you all gone mad?" Thanks to him, a curious few rediscover the joy of singing their own song and showing their own colors.
