The Salton Sea, California\'s largest inland lake, supports a spectacular bird population that is among the most concentrated and most diverse in the world. Sadly, this crucial stopover along the Pacific Flyway for migratory and wintering shorebirds, landbirds, and waterfowl is dangerously close to collapse from several environmental threats. This book is the first thoroughly detailed book to describe the birds of Salton Sea, more than 450 species and subspecies in all. A major contribution to our knowledge about the birds of western North America, it will also be an important tool in the struggle to save this highly endangered area. Synthesizing data from many sources, including observations from their long-term work in the area, the authors\' species accounts discuss each bird\'s abundance, seasonal status, movement patterns, biogeographic affinities, habitat associations, and more. This valuable reference also includes general information on the region\'s fascinating history and biogeography, making it an unparalleled resource for the birding community, for wildlife managers, and for conservation biologists concerned with one of the most threatened ecosystems in western North America.
