The American Birding Association Field Guide to Birds of Pennsylvania includes over 252 species birders are most likely to see in the commonwealth. Illustrated with over 400 crisp color photographs, it includes clearly written descriptions along with tips of where and when to see birds by an expert birder.

George Armistead is the events coordinator for the American Birding Association. While guiding birding tours for Field Guide, Inc. he led trips to all seven continents, but today enjoys seeking birds and photographing them in his native Philadelphia.
