Written for beginners and experienced birdwatchers, this field guide identifies 990 species of birds in North America. Dunn, a consultant and specialist in the identification and distribution of North American birds, and Alderfer, a birding artist, author, and field guide illustrator, detail the physical characteristics, voice, range, and geographic area for each species by group, with maps and color illustrations on the facing page. This edition has 23 new species and updated classification according to the newest American Ornithologists' Union Checklist, as well as 300 new illustrations, with field-mark annotations and images of birds resting, roosting, swimming, and flying. It has updated maps, including 40 subspecies maps, which include migration ranges and larger subspecies maps; some species have separate breeding range and winter maps. The guide has been redesigned to expand coverage of vocalizations, range, and geographical variation. Annotation Ac2012 Book News, Inc., Portland, OR (booknews.com)
