The Sibley Field Guide to Birds of Western North America, First Edition

Very Good paperback (flexi-binding).  Binding is tight. Small creases to edges of cover. Small chips to edges of spine.  Small stain on top corner of back cover. 

North America's finest field guide in a new portable format. This is the first edition of Sibley's portable field guide to birds of western North America.  It covers the identification of 703 species of birds (plus certain regional forms) found in western North America. It uses the same beautiful artwork from the original Sibley Guide to Birds. The voice descriptions are simplified from the original larger book, and a sentence or two was added to each species describing the general status and habitats. Maps completely revised.
