A sighting in the field is just one way birders can identify bird species.

This fully illustrated guide-the first of its kind for North American birds-presents thorough and straightforward instruction for identifying bird families or individual species by careful examination of the unique sign they leave behind. It also offers keys to the birds' behavior in the wild.
