How to identify predator sign in the field?

Recognizing Tracks

When identifying predator sign, tracks are a crucial starting point. Different predators have distinct track shapes, sizes, and gaits. For example, a mountain lion’s track typically measures 4-5 inches long and 3-4 inches wide, with a distinctive “C”-shaped toe impression. In contrast, a coyote’s track is smaller, measuring 2-3 inches long and 2 inches wide, with a more rounded toe. To accurately identify tracks, look for the number of toes, toe shape, and the overall size and shape of the track.

Scat and Other Indicators

In addition to tracks, scat and other indicators like digging or denning sites can provide valuable information about predators in the area. Scat can be an especially useful indicator, as different predators leave distinct scat patterns. For example, coyotes tend to leave small, loose scat, while mountain lions produce larger, more compact scat. Denning sites can indicate the presence of predators that dig burrows, such as coyotes or foxes. These sites often feature shallow, cone-shaped entrances and a network of tunnels and chambers.

Interpreting the Evidence

To accurately interpret the evidence, consider the context and location of the signs. Look for patterns and combinations of signs that suggest the presence of a specific predator. For example, multiple coyote tracks near a denning site may indicate a breeding pair or family group. Similarly, a single mountain lion track near a hunting area may suggest a solitary individual. By combining track, scat, and other indicators, you can develop a comprehensive understanding of the predator population in the area and make informed decisions about trapping, hunting, or conservation efforts.
