Instructions
Inspect the size of the scat. Larger animals will leave larger piles of scat behind. For example, a bird will leave a small pile while a bear will leave a very large pile. Use your field guide to eliminate animals that aren't the right size.
Compare the shape of the scat to the scat profiles in your field guide. The shape of the scat will tell you a lot about the animal. Carnivorous animals have cylindrical scat while herbivores have small, round scat.
Look at the shape of the scat pile. Animals such as deer or birds leave scat as they move, leaving long trails. Animals that sleep in one place, such as bears, often eliminate in a very specific spot away from their den, resulting in large, neat piles of concentrated scat. Check your field guide for animals that leave scat in this method.
Check the color of the animal scat. Carnivores have dark scat that matches the meat they eat. They also often have fur in their scat. You might see small plant parts in herbivore scat and the color may vary depending on the type of plants the animal ate.
