Track Tracks are small, blurry marks, often showing drag mark of tail. Shrew tracks are seldom seen and are usually composed of only a few dots in dust, snow or sand.
Sign Small burrows that are wider than high. Snail shells piled under logs. Tracks and other signs are of limited usefulness in identifying shrews, both elements are tiny and not distinctive. Burrows are often so small they might be mistaken for tunnels of large earthworms, and prints are often blurred dots. Those interested in identifying the whereabouts of shrews should look for tiny burrow openings in the ground, in a bank, or in moss, or for runways of freshly disturbed soil under a log or under the lip of a bank.
