Birds of Pennsylvania
This edition has the same easy-to-use qualities as the first, but with a great new feature. It is designed with the audio track number at the bottom of the page so the user can read about the bird and then go right to the track number to hear the sounds it makes. But, while designed as a companion fo the audio CD, the book can be enjoyed, as always, on its own. Also included are new sharper images and additional photos of juveniles, morphs, and more.
