"Mammal Tracks & Sign, A Guide to North American Species" by Mark Elbroch has much in common with his bird guide, "Bird Tracks & Sign", in terms of its amazing thoroughness, honesty, clarity, and a surplus of fantastic drawings, diagrams, full-color photos, photo comparisons, gait analysis, animal size comparisons, scat comparisons, feeding sign comparisons, personal anecdotes, methods of approaching tracking, ecological tracking, and on and on. There are other great tracking guides out there - but this one is head and shoulders above any of them. It almost gives you a sense of being the first of a new generation of books about tracking. 5.5" x 8.25", index, bibliography, resource list, tracking courses listing, hefty book at 779 pages.
