The Warbler Guide, Princeton University Press and the Macaulay Library at the Cornell Lab of Ornithology have released an awesome audio companion for the book. The authors, Tom Stephenson and Scott Whittle, have taken what was already an amazing book and made it much better with this addition. I had originally felt that without actually having the audio, the sonograms were somewhat difficult to understand if you had not seen them before. Now, with the audio companion, it is very easy to compare the sonograms with real audio of the species. This creates the opportunity to not just learn the warblers by sight with The Warbler Guide but also the songs, calls, chip notes, and flight calls!
