Otter? Mink? Fisher cat? Not sure what else there is to choose from in New England.

Regardless, this little gal/guy was scampering on the ice yesterday outside our office. I didn't have a zoom lens and this was shot through a not-so-clean double-pane window (it's cold out there!). Shortly after the shot it slid into the cold Mascoma river, swam about a third the way across, and then dove under water.

I'm still waiting for it to come back up...

A couple weeks ago Jeff passed along a link to an Ermine video from his friend who works up at the Sunkhaze Meadows National Wildlife Refuge in Maine. Here's a page of their videos.
