Title: The bible for all serious birders
Review: This is the most complete book on identifying birds by sight and sound that exists. Regional and age-based plumage variations are all illustrated, as are hybrids. Important features are highlighted, flight patterns are shown. The birds are illustrated both perching and in flight. Every detail is perfect. My only criticism is that it's completely lacking in behavioral information. And the book is too large for convenient use in the field. I could not live without this book.
