In 1838, John ames Audubon’s Birds of America was one...In 1934, Roger Tory Peterson produced Field Guide to the Birds...Now comes The Sibley Guide to Birds.”Thus did The New York Times, in 1999, greet David Allen Sibley’s monumental book, which has quickly been established nationwide as the peerless, standard bird identification guide. The Sibley Guide to Bird Life and Behavior is the new landmark book from David Allen Sibley. Designed to enhance the birding experience and to enrich the popular study of North American birds, the book combines more than 795 of his full-color illustrations with authoritative text by 48 expert birders and biologists.
