I found this book to be informative as a guide to what I would find in Europe, but it received a poor grade in the field due to the poor organization. I had to flip through three sections to find a picture, description, and range-map for each bird. The maps were really too small for a US native to be able to tell which country was which, and the illustrations were consistantly exagerated to the point that you could only identify the so-called important features (which often were the same as important features of other birds) were all you could be certain were accurate to some extent. Even though I don't speak German, I actually found a book in German which was more useful to me than Peterson's. The German book, entitled GU Naturfuhrer "Vogel" (Birds), had accurate photos of every bird I saw on my trip. The maps in Vogel, although lacking lines seperating the countries, were much more identifiable to an American due mainly to size. After identifying the birds by the photos, I compared the scientific names to Peterson's, and was able to identify the birds with their English names (although usually the pictures in Peterson's looked nothing like those in "Vogel"). So as a field guide, Peterson's gets no stars, but for the descriptions and scientific names, it deserves a little credit.
