“ It is commonly said of the peacock that it has an angel's feathers, a devil's voice, and a thief's walk. The crow-peacock is proverbial. [471] The peacock hides itself when it becomes ugly; so does the sky, and so does the sun when the autumnal clouds cover it; but in the summer clouds the thunder rumbles, and thunder made upon the primeval races of men the impression of an irresistible, much-loved, and wished-for music, resembling the song of the melodious kokilas (the cuckoo) , or of the watercock (the heron, the halcyon, the duck, or the swan) . ”
