Peterson Field Guide to Birds of Western North America

With all-new range maps, updated text, and 40 new paintings, the completely revised editions of two classic Peterson Field Guides are sure to be valuable additions to any birder's pocket or daypack. At a trim size of 5 x 8, they are portable but also beautifully illustrated. Photographs, while modern looking and colorful, capture just one moment in time. The paintings in these guides, however, show all of a bird's key field marks and use the Peterson Identification System to make bird identification easier for beginning and intermediate bird watchers.
