Birds of Southwest Arizona and Southeast California
by Greg R Home.
Birds of Southwest Arizona and Southeast California by Author Greg R. Homel is a quick and easy-to-use, lightweight, durable, all-weather field guide to the inspiring and remarkably varied birdlife of the desert southwest. Unlike most guides to the region, this guide does not stop at artificial state lines; instead, it treats a representative sample of birds inhabiting Southwestern Arizona's and Southeastern California's portions of the great Sonoran and Mojave deserts as a whole, bisected by the Lower Colorado River Valley.
