With more than 300,000 copies already sold, Backyard Birdsongs is back by popular demand. The Cornell Lab of Ornithology is proud to rerelease this widely acclaimed bird audio field guide series, from award-winning ornithologist and author Donald Kroodsma. Suitable for beginning bird watchers, Backyard Birdsongs is an interactive handbook of birds and their songs. With a touch-button electronic module that contains common vocalizations of seventy-five species from across eastern and central North America, this volume offers a truly sensory way to identify and get to know local birds. Crisply detailed, scientifically accurate illustrations accompany each entry, and up-to-date range maps provide clear geographical reference points. With an introduction that will inspire readers to look out their windows and venture into the field, this unique book gives people of all ages an exciting entryway into the subtle art of using birdsong to identify birds. This second edition includes a much-requested new Sound Track Index (to help make watching and listening to birds easier), and access to a free download of the Cornell Lab's own MERLIN® Bird ID App (in iTunes and Android stores). As with all Cornell Lab Publishing Group books, a portion of the net proceeds from the sale of Backyard Birdsongs supports projects at the Cornell Lab, including children's educational and community programs.
