Birds at RestA wide ranging account of how birds spend the quiet half of their lives Birds at Rest is the first book to give a full picture of how birds rest, roost, and sleep, a vital part of their lives. It features new science that can measure what is happening in a bird's brain over the course of a night or when it has flown to another hemisphere, as well as still valuable observations by legendary naturalists such as John James Audubon, Alfred Russel Wallace,
