The tracks above belong to a mouse (Mus sp., Muridae). When moving quickly they hop along and leave large footprints with their rear feet. They also tend to leave streaks where their tails drag along behind them. The smaller print between and slightly behind the top set of footprints was made by the front feet. The direction of travel was towards the top of the photo, but the hopping movement results in the rear feet landing in front of the front feet.
If the snow is deep enough they can travel just below the snow surface, creating a long collapsed trail behind them. The emergence of unmistakable mouse tracks from the trail above made it clear who was responsible.
