A Field Guide to Western Birds, The Peterson Field Guide (Used Hardcover) - Roger Tory Peterson

This is the first practical guide to the outdoor identification of birds regularly found west of the Rockies.   It does for the West what Peterson's widely used "Field Guide to the Birds" has done for the East.  The Rocky Mountain States, the Pacific States, the Pacific Northwest and the Southwest are all covered.
