From the publisher:

From the renowned author of the New York Times best seller The Sibley Guide to Birds, a comprehensive, beautifully illustrated guide to identifying birds in the field. Sibley's Birding Basics is an essential companion for birders of all skill and experience levels.

With Sibley as your guide, learn how to interpret what the feathers, the anatomical structure, the sounds of a bird tell you. When you know the clues that show you why there's no such thing as, for example, "just a duck" birding will be more fun, and more meaningful. An essential addition to the Sibley shelf!
