"Undoubtedly the finest guide to North American birds."-Guy McCaskie, Birding The publication of The Sibley Guide to Birds, First Edition quickly established David Allen Sibley as the author and illustrator of the nation's supreme and most comprehensive guide to birds. Used by millions of birders from novices to the most expert, The Sibley Guide became the standard by which natural history guides are measured. The highly anticipated second edition builds on this foundation of excellence, offering massively expanded and updated information, new paintings, new and rare species, and a new, elegant design.
