The Pocket Guide To Animals / Tracks is a guide that you can truly put in your pocket and not worry about getting wet or dirty. It provides illustrations of key animals and birds, with their tracks shown alongside. Because it is spiral bound and tabbed, you're able to get in and out quickly as you come across puzzling indications of big game, small game, or birds. Along the margin is a ruler that enables you to quickly size a track. This guide is a must for hikers, backpackers, birdwatchers, and hunters.
