Mysterious Tracks In Snow

First I thought these were a small bird, but I quickly realized it was something different. I have seen a lot of different tracks in my career, and can usually surmise the source. This time, I am stumped.



Mole? I don't think so. The scale seems wrong and this creature was very active above the surface.



What makes the radiating pattern?



These were all over the place, in an open field right next to a bit of forest. It this is a small mammal (as I suspect), then it would be a prime target for birds of prey in this environment.



I need to call in the experts.
