Preface (p. vii): Those of us who have read Ernest Thompson Seton's semi-autobiographical story, Two Little Savages, remember how the young hero, Yan, discovered some mounted ducks in a dusty showcase and how he painstakingly made sketches of their patterns.
How to Use This Book (p. xvii): Veterans who have watched birds for years will know how to use this book.
As the first of Peterson's guides, the guide to Eastern North America (sometimes titled Eastern and Central or East of the Rockies) was, in its earliest edition, titled simply Field Guide to the Birds. That title should remain with the eastern guides and should not be combined with the new Guide to the Birds of North America, which covers the entire region.
The paperback version of the 4th (1980) edition carries variations of three different titles: (1) Eastern Birds - Front Cover and Spine. (2) A Field Guide to the Birds of Eastern and Central North America - Inside Cover. (3) A Field Guide to the Birds: A Completely New Guide to All the Birds of Eastern and Central North America.
