"A highly significant contribution to the field. Wheeler has accomplished what no other guide has done for any group of birds. The quality of photography, scope and depth on plumages, races, and variations, are unequaled. The range maps are stellar--the best ever done for any guide. It is the ultimate raptor reference and will be for decades to come."--Clay SuttonWheeler, Brian K. is the author of 'Raptors of Eastern North America The Wheeler Guide', published 2007 under ISBN 9780691134765 and ISBN 0691134766.
