Everything perfect in its kind has to transcend its own kind, it must become something different and incomparable. In some notes the nightingale is still a bird; then it rises above its class and seems to suggest to every winged creature what singing is truly like. – Johann von Goethe

I value my garden more for being full of blackbirds than of cherries, and very frankly give them fruit for their songs. – Joseph Addison, The Spectator, 1712

Have you ever observed a humming-bird moving about in an aerial dance among the flowers – a living prismatic gem…. it is a creature of such fairy-like loveliness as to mock all description. – W.H. Hudson, Green Mansions
