Gary Young in his book, No Other Life:
Hummingbirds build their nests under the ferns; little cups of lichen, feathers and moss. They cannot walk, but they can hover in the air. They can fly forward, and fly back, and when they move into the light, their frail bodies shine with iridescence. Watching them in the garden, my own voice startles me by saying, look, there's my heart.
