This book is the first ever, comprehensive photographic guide to the identification of all 24 species of hummingbirds to be seen as breeders or vagrants in North America. Steve Howell, a well-known and respected bird tour leader and author, has made a particular study of the finer points of hummingbird recognition and has specially chosen over 200 stunning photographs to complement the information given in his text. Some species feature as many as 14 photographs each. A detailed introduction covers the basics of hummingbird anatomy and plumage variation, allowing the observer to effectively focus on points that are of value in the field. New field marks are provided and old myths dispelled in this ground-breaking and essential new guide.
