Waterfowl can be identified by using information about size, shape, color pattern, markings, behavior, habitat, range and calls. All clues are important, but by far the most important things to concentrate on for this group are shape and patterns of white. This guide features more than 25 species of ducks and includes both silhouettes that emphasize distinctive shape and placement of white, and full color images of both males and females. Sections address behavior, habitat, color patterns and other characteristics important for each species. A portion of the proceeds from the sale of this guide support continued educational activities by The Cornell Lab of Ornithology. Made in the USA.
