I was also intrigued by a set of meadow vole tracks and runs as well as little hole dug in the snow with scat deposited. I followed the tracks and tried to figure out what was happening. At any rate, the tracks came out from under the snow on the edge of the old field, ran into the open, circled around a bit, then the hole was dug and the small pile of scat left. The tracks then headed north on the surface for about a metre before they turned into quite a significant "run" (like a tunnel without the roof). This pattern of traveling over the surface, then within a "run", carried on for about 100 metres, before the tracks veered back into vegetation and stopped at the entrance of a snow tunnel beside a tree. Dog and human prints disturbed the pattern in places, other wise I might have tried to get a video clip of the whole thing. Not entirely sure what was going on, but oh well, it gave me something to look at, and gave Tasha time to sit. Meadow voles are far less likely to travel across the snow surface in winter than mice are, but this doesn't mean they never do it. Just that they are more adept at tunneling beneath the snow.
