content: The "search inside" feature of this ad shows gorgeous, color photographs of the birds; HOWEVER, the actual book's photos are in black and white! Admittingly, the photos here are more accurate than Dover's older version's drawings, but you will still need to refer to another source for color photos/drawings. If you already own an older copy, don't bother with this one! If you are buying for the first time, you will appreciate the large, clear photos, but know that they are all in black and white.Spacing of the text is another problem I have with this publisher's version. The lines of text are too close together for easy reading. Dover's version is easier on the eyes.
