A sighting in the field is just one way birders can
identify bird species. Observant nature-lovers can discover what birds are
where by examining tracks, trails, and a variety of bird sign: discarded
feathers, feeding leftovers and caches, pellets, nests, droppings, and
skulls and bones. 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.
