Beautiful clear crow tracks in snow.

I was curious about the sharp right turn. However, the end of this trail pointed to several bluegill carcasses left by otter or raccoon on the rocks of this drainage area, by open flowing water.

Points in favor:
1) Look closely at the 1st photo. There is one complete, clear track there showing 5 radial toes, tall negative space, and a trapezoidal mesopodial pad. It measures about 2" L without the carpal pad.
2) 2nd & 3rd photos show a well used trail leading into a small, round hole under the large rocks of this drainage area. I can easily see an otter slinking into this gap; I can't see a raccoon squeezing in there.
3) Multiple fish carcasses (bluegill) litter the rocks in various stages of dismemberment.

The second of three mysteries from tracking club: What is this??

Ruled out hopping bird: I see >3 toes pointing forward.

Possible candidates:
Squirrel: possible carpal pads in one track? However, the bound pattern isn't right, and toe structure is off.

Weasel: I can't believe I didn't think of this in the field. Furry feet, about the right size, 2x2 bound. Hot dog.

Track parameters: I see one track of at least 1" in length, putting this in the middle of the range for long-tailed weasel.

Seeking second opinion, please.

Buckle your seat belts, trackers. This one was a mess o' fun, and I need a second opinion.

Group Discussion:
One participant thought the track/trail in photos 1&2 was mink. I felt we could rule out mink given:
1) track size >2" L, well above mink track parameters
2) morphology of hind paw with distinct heel, and
3) group length. The participant made the case for the lower left track in photo #2 being the same animal & trail of the track in photo #1. Inn that case, group length is 7.5", beyond the range cited for mink 2x2 bound in Poppele guide.

This just didn't look like a mustelid bounding trail.

My case for raccoon:
Clear toes with long heel present for hind foot (~2.5" L)
Clear toes with smaller compression for front foot (~1.75" L?)
Reasonable stride length for raccoon walk
Context: there was a clear raccoon trail leading perpendicular under log to this point. (There were also muskrat trails moving underneath the log, parallel & perpendicular, you can see in the context photo).

This is a direct register walk rather than classic overstep walk, but we've seen this track pattern before with raccoons in snow.

Last photo is a close-up of the lower left track in the second photo, which does show three teardrop-shaped mink-like toes - but this was the only track seen with that characteristic. We also only see three clear toes, with a width >1". The more I look at it, the more I don't think it's associated with the upper right larger track -- those toes just don't look the same. The width of the foot leans me to muskrat on this track, as does the body trough to its right & many nearby muskrat trails.

I welcome feedback from more seasoned trackers!

Whose fur? It's quite soft & dense, dark gray with cinnamon colored tips.

I think this is meadow vole:
1) location is spot on in voletown
2) it's the most prevalent mammal in this location
3) ruled out: deer mice (greyish fur), cottontail, mole (short, uniform gray velvet), squirrel (longer fur, lighter base color).

And bonus question: who killed this critter? Fur attached to small strips of skin was scattered in a 7' ring in this marshy cattails area, around a dead trunk. A coyote had come through, but had not paused -- and coyote, fox, bobcat, and owls will eat voles whole. A weasel would cache the vole before feeding under cover.

I believe that leaves a hawk, feeding on an unfortunate vole on the branch of that dead tree.

He passed this way since the snow, but his trail had been trodden by smaller, more recent coyote prints. Only a few clear wolf tracks remained.
