Thank you for sharing those, Bob, and thanks Al for the breakdown of indirect register!
I found a few more during the snowfall last weekend, plus I dug two out of the archive from last year to share if anyone is interested:
First, what I believe to be a fox 'dive' into snow while hunting a rodent. Head size and size of tracks seemed too small to be coyote.
Also, a squirrel kill from a raptor. I've been advised that it was a hawk, since owls will typically remove the head. I'm also told that you can tell if it's owl or hawk from the uric acid spray from the base of the tree, which I didn't see at the time.
White-tailed deer, with print on right showing dewclaws:
I should have put a coin down for scale for the next one. These were tiny, they almost looked like they were invertebrate tracks, but it was brutally cold after the snow. Any takers on this one?
Rabbit, probably running. I believe so because the bound was nearly 4 feet!
This one tricked me. A cursory look at the front paws side-by-side, plus the fact that the trail seemed to originate at the base of a tree, made me think that I was looking at Eastern gray squirrel prints. However, I realized later that the front prints were registering in front of the hind, making this a rabbit track. Interestingly, the bound was a bit shorter and in the opposite direction as the one pictured above, so I'm guessing that he ran into a fox and took off in another direction, and the tracks pictured above are of him running from the fox (there were also fox tracks near the rabbit tracks, see below).
Here is the rabbit trail, looking relaxed and unlike the trail 2 pictures up. Note the bound was about 2 1/4 feet, vs. the 4 foot stride when running:
Here are the fox prints:
Measuring the stride:
Here is the fox trail, showing how deliberate the trail is (center of picture):
