The Long-tailed Weasel American Mink

[Well, I’ve been corrected by several readers as to the identification of this mammal. Having read regular reports of Short-tailed Weasels at this location, and not having heard of a Mink being sighted there, I made a wrong assumption. My thanks to the folks who set me straight. -Marc Hoffman]

I had a fun surprise yesterday while watching a female Common Merganser as it swam, preened, and fished along the weir at Marymoor Park in Redmond, WA. In the background, I noticed a tiny, otter-like head poke up and swim across the strong current. As it climbed onto the rocky shore, I could see it was a Long-Tailed Weasel an American Mink.

American Mink, Marymoor ParkAdult Mink measure about 12-18 inches long. They spend much of their time in or around water, swimming with an undulating motion of the body. Adept hunters, they feed on fish, reptiles, amphibians, birds, and other small animals, often delivering a fatal bite to the head or neck. Audubon reported seeing a Mink carrying a foot-long trout.

Mink have been farmed for their fur. They can be kept as pets but are known for biting their owners, so must be handled with gloves.

Still, they’re awfully cute, don’t you agree?

    Cool pics Marc, but the dark brown color, dark underparts with just a hint of white on the chin, burly (for a mustelid) silhouette, and behavior make me think mink (Neovison vison), not weasel.

    Also very cool creatures to see in the wild – I still remember how freaked I was the first time I saw one trotting along the bank of the lower Yakima and then diving right in.

      Roy, I am convinced you’re right. I had not heard of Mink being seen in that area, only regular sightings of Long-tailed Weasels. I have since learned there have been a handful of reported Mink sightings over the years. I will be revising the blog post to reflect that. Thanks for the correction–always appreciated!

      Thanks, Catherine! At the moment of that first shot, the Mink was about 12 feet away and walking straight toward me. They don’t get much more cooperative than that 🙂

    I have such a thing for mustelids but have never gotten more than a brief glimpse. How fortunate you are. Thank you for sharing.
    Safe passages Mr. Mink!

    Hi, Marc, I saw your comment on the Tweeters list and came over to look at the weasel … I mean, mink photos. 🙂 Wonderful! I love these serendipitous sightings, particularly of minks, otters and weasels, since their furtive nature makes the encounter that much more spectacular.
