Tracks number one (above). Quite certain this is mouse. Where snow was deeper, they created marks that looked more like open tunnels.
Tracks number 2 (above). Cottontail rabbit who places his front feet close together.
Sometimes the tracks criss cross over each other. I'm taking a wild guess that the animals weren't actually out there at the same time.
What are the most interesting tracks you've seen on your property? What are the most common?
