Here are more tracks in the snow, from our mystery visitor. Here, he or she is coming and going along the same path.
And here is my own size 6 boot print, next to the tracks, to provide scale.
Minikat identified the tracks correctly. They are raccoon tracks. I was not aware that we had raccoons in this area, until I saw a dead one along a street last summer. I have named our visitor "Rocky" from the Beatles song, "Rocky Raccoon". However, I also call him "Ranger Rick", but Ed does not understand that reference. It is the name of a kids' nature magazine, from the National Wildlife Federation, and Ranger Rick is the mascot--a raccoon. When I was in grade school, my best friend Kathy had a subscription to the Ranger Rick magazine, and I was so envious. It is cool that the magazine still exists. Funny how both names bring back memories of my childhood. I learned the Rocky Raccoon song from Girl Scout camp counselors. We never saw raccoons at Girl Scout camp, but we did see bear prints on an outing and later saw a baby bear. We didn't stick around long enough to meet its mother. Ah, good times!
