Have you ever wished you could distinguish the song of a wood thrush from that of a hermit thrush? Kroodsman's new book combines his personal observations of birds with scientific descriptions of how they develop their songs. Accompanying diagrams show the pitch and relative loudness of the notes in a bird's song, and the book includes a CD with nearly 100 different examples. Kroodsma's enthusiasm will help even novice bird-listeners appreciate the subtle harmonies of their feathered friends.
