Trackards for North American Mammals contains twenty-six Trackards. Twenty-five of these cards include images of one or more life-size tracks of selected North American mammals that are distributed widely over the continent. The twenty-sixth card contains a representative variety of commonly found tracks and sign of house cat, frog and birds. All images have been produced from photographs of actual tracks and scat of live, free-ranging wild animals. Additional illustrations of tracks, scat and other sign are presented in The Companion Guide to Trackards for North American Mammals (ISBN 978-1-935778-09-7) which also contains information about track morphology, the similarity of sign of one species to that of other species, and habitat preferences. No images have been copied from other sources, a practice that has perpetuated many inaccuracies in other tracking books and related resources.
The Trackards identification system has been field tested and revised for over a decade, resulting in the best resource on the market for the successful identification of mammal tracks. The cards are arranged in the deck according to track size. The first card has information about the species in the deck with the largest tracks, Black Bear, while the twenty-fifth card has information about the species with the smallest tracks, Vole and Shrew. If a species has front and hind feet of different size, the larger of the two dictates its order in the deck.
Terms and symbols used on the cards are defined inside the back cover of the deck.
Trackards are printed on synthetic stock and are completely waterproof, ready for use in any field setting.

David Brown
was born and grew up in Malden, Massachusetts, in an area surrounded by forest, rock outcrop and wetland. His lifelong interest in natural history began while roaming these woods as a boy. An avid birder from the age of twelve when he was stunned by the beauty of a Baltimore oriole that flew over his house, he once hiked ten miles to see a rare bird reported in a metropolitan park near Boston.
He is a graduate of Tufts University with a B.A. in English, a decorated Marine veteran of the Viet Nam conflict and a public school teacher of 20 years experience. Today he operates a wildlife services business and writes on natural history subjects and issues.
