This book is excellent for all people interested in birds. Unlike the Peterson books, this book has all birds of North America in one edition. Also, it has maps right next to the description of the bird so you don't have to go flipping pages to find it. It is fully illistrated, which in my opinion is better than photos because you it shows all the different plumages and if the light was off while the picture was taken, it might not look right. It shows all birds and if two look alike, it will tell you how to tell them apart. It shows pictures of male and female bird. It also includes sonograms of bird calls. The content of each bird's description is remarkable, telling how to attract it, etc. Golden Books has done a wonderful job on this book.
