Enhanced descriptions from Syndetics:

The best-selling field guide since 1934, the Peterson Field Guide to Birds of Eastern and Central North America features clear, succinct accounts of more than 500 species, accurate and beautiful paintings on 159 color plates, and 512 maps annotated with extensive range information, making this the most accessible field guide for bird watchers in eastern North America. Peterson Field Guides are valuable additions to any birder's pocket or day pack. At a trim size of 5 x 8, they are portable and 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. Expert birders have also created 35 entertaining and easy-to-use supplementary video podcasts, which are available to download.
