Field to the Guide Birds of Western North America

This new field guide covers the avifauna of western North America. It uses artwork and maps from the highly successful North American Bird Guide, accompanied by a new, more detailed text. The reduced size of the area covered means that this guide is considerably lighter than the original book, even with the expanded text. This book is lightweight enough for regular field use, and the fully integrated format enables quick and easy reference and comparison to be made.
