Bird Tracks & Sign

A Guide to North American Species

Birders and nature-lovers don't need to see a flash of color or hear a snippet of song to learn of a bird's presence and determine its identification. This richly illustrated full-color guide -- the first of its kind for North American birds -- offers thorough and straightforward instruction for identifying bird families or individual species by careful examination of the unique sign they leave behind in the wild.

Observers 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. Also offers keys to the birds' behavior in the wild. Includes songbirds, waterfowl, owls, shorebirds, warblers, woodpeckers, nightjars, and birds of prey. For trackers, birders, and nature-lovers.
