Thanks Clifford. I was lucky on this one. Most often they are so fast and wary that getting anything is a plus. This one made half a dozen trips across the ice back, and forth before it caught the sound of the mirror in the camera.
One of the many American Mink that I see all along the shore of the Speed River here, in Cambridge Ontario. Even after it became aware of my presence, it continued to forage back and forth from the river, to its den.
