When you have found a bird’s nest, you have found him out. You have found the very center of his life, and his dearest secret. In the case of small, ground-nesting birds especially, the difference between secrecy and discovery is the difference between success and failure, life and death, continuance and oblivion…Small wonder that birds hide their nests with every last evolved instinctual whit of cunning that they have.
