American Marten (Martes americana), also known as a Pine Marten, in the snow on Hudson Bay Mountain near Smithers in Northern British Columbia. Martens normally eat small mammals such as squirrels and rodents. They are however related to the wolverine and capable of hunting much larger snowshoe hares and marmots.
I was lucky enough to see this guy out of the corner of my eye while I was snowboarding. He ran down a tree well; so I boarded over, took my backpack off, got my camera out, changed out the wide angle lens for the 400mm, and waited. After sitting there quietly for a few minutes he then popped his head up again.
