Because fish make up a large part of their diet, North American River Otters live along streams, lakes and wetlands. Although crayfish, hibernating frogs and turtles, insects and other aquatic invertebrates are also consumed in the winter, the telltale identifying feature of otter scat (spraint) this time of year is the presence of fish scales.
Look for otter scat on raised areas near water, especially the shortest distance between two water bodies or on peninsulas. It is usually found on the ground, but occasionally on logs and at the intersection of two streams. Otters frequently form large latrines of multiple scats.
