The mink was moving amongst a windrow of ice pieces that had blow up along the length of the shore. The wind have created tunnels amongst the pieces. I ended up running along for about 1 Km trying to stay a few metres ahead of the mink and getting ready to take a shot whenever it popped up.
Taken handheld using my 500mm F4 + 1.4 teleconverter.
The American Mink (Neovison vison) is a member of the Mustelid family link the otter, skunk and weasel.
