We could make one really tiny coat.
That
is
a
Mink.
That tail is not an otter tail. That nose is not an Otter nose. That head is not the shape of an otter head. Those eyes are mink. That fur is not otter. Add it up and you don't get otter and certainly not a young otter alone in spring as posted above.
You sit on my patio and you can eventually see beaver, otter, mink, pine marten, fishers, porcupine, muskrats and others. Mink are easy to ID once you learn their face. Also their fairly solid brown color is somewhat unique compared to the others.
I have seen large mink just like the one in the pic. It surprised me as well, I am use to seeing smaller ones. I have never asked the DNR guy about the escaped mink. There are still some active mink ranches up here.
