Bird Tracks & Sign: A Guide to North American Species

This comprehensive field guide will prove invaluable to naturalists, birders, and trackers who are often only given "bits and pieces" of a story. The full-color guide includes bird tracks, trails, feathers, feeding signs and caches, pellets, nests, droppings, and skulls. Hone your own tracking skills or enhance interpretation on hikes or tours of nature center collections. Bird Tracks & Sign will enable you to key out the bird species that left tracks or other sign.
