Scat Finding

This scat appeared to be at least 1 day old and was located on the middle of a rock in a dried stream bed trail crossing. I used a quarter as a size reference as quarters are approximately 1'' in diameter. The size is roughly 4'' long and 3/4'' wide with one end tapered. It contains white or light gray colored fur.

According to The Complete Tracker - The Tracks, Signs and Habits of North American Wildlife by Len McDougall, Coyote scat is generally between 3'' to 4'' long and 1'' in diameter. In Tracking and the Art of Seeing: How to Read Animal Tracks and Sign by Paul Rezendes, Coyote scat is said to be between 1/4'' to 1 5/16'' in diameter. Coyote scat is often filled with animal fur, is tapered, and is frequently used as a territory marker, thus it is deposited in commonly traversed areas such as on trails. The scat I found matches precisely the size, shape, composition, and location of Coyote scat.
