I struggle with differentiating mouse from vole tracks when behavioral clues are not obvious. Voles, at least the commonest of souther New England, baseline movement (sometime known as harmonic gate) is a trot while mice move in a bound most of the time. Of course they are each capable of both gates as well as others. There are distinctions in the foot morphology but I have not looked at enough clear tracks of these species to reliably see these differences with confidence.
The creature in these pictures moved in a protected area close to cover most likely exploring the cracks and holes in the frozen sand at the bottom of a big eroded drainage. All kinds of things blow in there from the sand barren-like wild blueberry fields above.
The measurements I took fit into several mouse and vole species. Some of the morphology is apparent but not consistent. In some sets the right foot looks different than the left.
If I have it right the toes of voles show more connection to the pads giving them a finger like appearance. I don’t really see that in these tracks. These do however walk a great deal like a vole is more likely to do.
There were a few bounds mixed in as well.
Every time I think I got this tracking thing licked I find something else to learn.
