This bestselling field guide features a durable vinyl binding and brilliant full-color photographic identification pictures arranged for quick access and definitive text, including information on the bird's voice, nesting habits, habitat, range, and interesting behaviors. Accompanying range maps; overhead flight silhouettes; and sections on bird-watching, accidental species, and endangered birds make the National Audubon Society's Field Guide to North American Birds the most comprehensive available.
