Shrew, Mouse, and Vole Trails

I still get confused between Shrew, Mouse and Vole trails. A couple of mornings ago, when we got a fresh coat of snow, I could look down and see some pretty clear trails running perpendicular to the path I was walking on. They were small, had tracks of feet, and some showed tail drags. Some were hoping, some walking. While I looked at them I realized that I wasn’t 100% on which species or group of species they belonged to.
In light of this conundrum, I thought it would be worthwhile to put a little post together to help me better learn what to look for. Here goes.
