Summary
Backyard Birdsongs is an interactive handbook of birds and their songs for beginning bird-watchers. With a touch-button electronic module housing common vocalizations of 75 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 and scientifically accurate illustrations accompany each entry, and up-to-date range maps provide clear geographical reference points. This second edition includes a much-requested new Sound Track Index (to help make watching and listening to birds easier), and a free download of the Cornell Lab's own MERLIN™ Bird ID App.
