The Peacock and the Crane.

A Peacock, spreading its gorgeous tail, mocked a Crane that passed by, ridiculing the ashen hue of its plumage, and saying: "I am robed like a king, in gold and purple, and all the colors of the rainbow; while you have not a bit of color on your wings." "True," replied the Crane, "but I soar to the heights of heaven, and lift up my voice to the stars, while you walk below, like a cock, among the birds of the dunghill."

Fine feathers don't make fine birds.
