Tracking isn’t just the search for clear footprints. There are many more traces that animals leave behind. The search for these other indicators is called sign tracking, and it can be used in almost any environment. This method of tracking involves the signs, marks, disturbances, and leavings of an animal. Trails, beds, rubs, and chews can give a general idea of the species that are present. Hairs, feathers, and droppings can tell us exactly which animals are nearby. It’s important to learn to track by looking for these common animal signs, because in some terrains—it’s all you’ll have.
