Banff’s Snow Mammals

By March 10, 2021 No Comments

I used to collect stamps, and I still geek out sometimes when I’m at the post office. Which is exactly what happened last week when I saw a new set of stamps featuring snow mammals. Yes, snow mammals! These are creatures that turn as white as snow for the winter months.

What could be more apropos here in Canada? According to Canada Post, we are “home to more species of mammals that moult from shades of brown or grey to white than any other country in the world.” And I was happy to see that two of the five animals featured – the snowshoe hare and the short-tailed weasel – are found right here. On our snowshoeing trips, we find the tracks of these two all the time, but almost never see them.  Which is entirely the point, I suppose.

Come summer, the weasel and hare moult from white back to brown, to better blend in with the forest colour palette. I’ve spotted a few hares in their summer garb, and got lucky with this photo.

Alas, for weasels, including one that ran right through my legs, and another that had a chipmunk in its mouth, I found myself without a camera, so I don’t have a summer photo in my collection.  However, here’s a shot courtesy of Wikipedia.  This photo, by the way, is a least weasel, one size down from the short-tailed weasel. The Latin name of the least weasel takes the idea of snow mammals to a whole other level. What is it? Mustela nivalis, “weasel of the snow.”
