I'm having a lot of fun learning about red squirrel behavior in the winter. I have blogged about them frequently this season. In these photos, which will open full size in a new window when clicked (and I do think you should take the time to do so!), you see the squirrel digging with snow flying about. The yard and woods are full of the holes the squirrels use for moving about under the snow and those that they dig locating food.
You see the tufted ears popping out of the snow frequently. More humorous is when you only see the small, bushy red tail sticking up out of the snow. We can't see them if they can't see us?
