Bounding weasel

Weasels bound, so they make tracks that look like two little feet. But what really happens is they put their front feet down and then move their back feet into the same place where their front feet were as they bound forward.

My guess is this was a least weasel, because it was awfully small.

This weasel likely came through just before it started to snow yesterday, because its tracks are nearly filled in. There was a whole line of tracks just like these going from one side of the access road to the other.

Ermine (Mustela erminea), which is pronounced “er-men,” have three names. In North America, they are always called ermine or long-tailed weasels. In Europe and New Zealand, they are called stoats.

In North America, they tend to be found in the northern US and Canada, and most of them turn white in the winter.

Ermine coats are invariably of winter phase stoats from North America.

There is a related species called the long-tailed weasel(Mustela frenata), which is found from southern Canada to Bolivia. Some of the North American populations also turn white in winter.  The main difference between the species is that the long-tailed weasel has a significantly longer tail in proportion to its body size, and they are normally quite a bit larger. However, there is a size overlap.  The smallest long-tailed weasels are about the same size as the largest stoats. Long-tailed weasels are much larger than least weasels (Mustela nivalis), which are the smallest Carnivorans. Least weasels, like the stoat, are found in both Eurasia and North America, and they can even be found in parts of North Africa.

I have a long-tailed weasel in the freezer. It was killed in the late 90’s during squirrel season. It was chasing a rabbit when it was shot, and it was in the transitional phase between its winter and summer pelt.

Update:  I have uploaded photos in a post of my long-tailed weasel that I mention here.
