I saw this little guy in 2006, before I was really deeply into wildlife watching. I saw it at the Calgary Zoo, in Alberta, Canada. It was running through the portion of the zoo located on an island in the Bow River. Unfortunately I don’t have a photo of the tail, and memory serves me poorly as to how long it was proportionately. If anyone can surmise any clues as to the identity of this mustelid from this rather lackluster photo, I would appreciate it!
