This comprehensive guide to North American birds uses a fully integrated photographic approach for quick and easy identification in the field. This is the only photographic field guide you need to enjoy bird-watching in Western North America. It uses a photographic approach to profile the extraordinary range of birds found in Western North America. The highest-quality photography brings nearly 575 species to life on the page, capturing their beauty and making identification quick and effortless. The 367 species most commonly seen west of the Great Plains are featured in full-page profiles that emphasize all the information needed to identify them. All photographs are clearly labeled and annotated. Detailed similar species boxes make it easy to distinguish between birds that are similar in appearance. Schematic drawings show the shape and posture of the bird in flight as well as its coloration, and a diagram of its flight pattern is also included. A separate section profiles 128 species that are particularly uncommon or local in their distribution, and there is a short list of vagrants and accidentals--those that are, on occasion, pushed off course on migration to find themselves in North America. Written by experts and produced in collaboration with the American Museum of Natural History, Birds of North America Western Region is an essential field guide for identifying birds in North America.
