This book is the latest in a series of small pocketable guidebooks that focus on the west coast of North America. (Others include Birds of Southwestern British Columbia, Birds of the Puget Sound Region, Birds of the Willamette Valley Region, and Birds of the Los Angeles Region.) Birds of the Inland Northwest and Northern Rockies covers the identification of the common species of eastern Washington, eastern Oregon, Idaho, and western Montana. The book contains a “quick guide to local birds” (with useful small photographs) at the front and a very helpful “short index” and a longer “index/checklist of birds” in the back. Other introductory sections include a map, information on birding in general, identifying birds, attracting yard birds, bird habitats in the area, where to go to find birds in the field, and a useful list of resources such as journals, books, websites, stores, and nature centers in the area covered.
