The Sibley Guide to Birds has quickly become the new standard of excellence in bird identification guides, covering more than 810 North American birds in amazing detail. Now comes a new portable guide from David Sibley that every birder will want to carry into the field. Compact and comprehensive, this new guide features 650 bird species plus regional populations found east of the Rocky Mountains. More than 4,200 illustrations are accompanied by descriptive captions pointing out the most important field marks. This format is a real field guide, perfectly sized, durable, and filled with Sibley’s remarkably accurate illustrations. Ideal for anyone who can't distinguish among all those generic-looking "little brown birds" you always see at the feeder.
