A walk through the Lac Dubois grasslands presented an excellent canvas for tracking. Here we have a set of weasel tracks – possibly a short or long-tailed weasel, but at best it would be a guess.
The red lines denote the front and back feet, the blue lines denote the stride of the animal. You can tell the direction of the animal as the back of the track is the narrowest (in this case the weasel was moving from the bottom of the image to the top).
A jumble of tracks below shows at least three species: Red – a microtus (vole), Green – Peromyscus (deer mouse), Yellow – mustella (weasel of some sort)
