Like the other guides in the acclaimed series of International Bird Identification guides originated by Christopher Helm, Woodpeckers is comprehensive and definitive. It covers all 198 species of woodpeckers found throughout the world. Each is beautifully illustrated in color in its various plumages and described vividly and accurately, with complete information on its identifying characteristics, similar species, distribution, migration, habitat, geographical variations, voice, habits, food, and breeding behavior. References for further research are also included. Woodpeckers is an essential addition to any birder's library.
