Sibley Ducks Eastern North America

Written and illustrated by David Allen Sibley, America's most widely respected bird illustrator and ornithologist, these FoldingGuides offer instant access to just what birders need to know. Includes 50 species of dabbling and diving ducks, swans, geese, and duck-like species — both common and exotic — found east of the Rockies.

The foldout is laminated, so it's waterproof and wrinkle resistant. It would fit in a legal-sized envelope and will slip into a book or pocket for quick reference when you're out looking at waterfowl.

Each species is beautifully illustrated in color, with just enough text to clue you in what field marks to look for. There's also a little map showing where each species is found.
