Subfamily

Recent DNA studies have suggested that the traditional arrangement of family Mustelidae into two subfamilies based on morphological differences is invalid. Under this arrangement, the subfamily Mustelinae is polyphyletic (derived from more than one evolutionary ancestor.) Two molecular phylogenetic analyses in Sato et al (2004) and Koepfli et al (2008) suggest separating the family into eight subfamilies. Under their scheme, martens are placed in the subfamily Martinae. This suggestion has not been widely adopted.

 

Species

The same study also strongly suggests that the fisher should be placed in its own genus Pekania. This suggestion has been widely but not universally adopted. Fisher was formerly classified as Martes pennanti. It was reclassified as Pekania pennanti, and is now the only species in that genus.

Subordinate Taxa

Some authorities recognize three subspecies, while others recognize none.

Fisher Sighting on Trail Cam - Possibly

This is not a cat and the previous two cam images showed a dark blur as this animal leapt a couple times and then sat where the trail cam photographed it. After researching possibilities (marten, weasel, cat), the most likely animal that this appears to be is a Fisher. The size, body shape, and thick tail are not like any other animal.

A search of the Minnesota DNR website and other Minnesota sites shows that they have been seen in Houston county.

"Fisher photos".... An interesting animal larger than a mink....

It seemed curious about me and only got anxious when it wanted to come down out of the tree. I was below and it got a little nervous and started making these little chuckling sounds so I backed away and it came down the back of the tree peeking around keeping an eye on me and then scampered off away into the woods. I did not seem threatening at all.

About

Fishers are members of the weasel family. They sometimes get a bad rap as a vicious, dangerous animal. While they can be vicious in surviving in the wild they usually are not a threat to humans. I am in their territory a lot and have followed their tracks in winter and yet have only seen them a few times. This fisher got a little anxious wanting to come down out of the tree, so I backed off and let him down. He had sat there peacefully for several minutes not minding me at all.

This pair (mother and kit; id'd by an expert on Fishers) was found by Elias Elias along the Arcata Ridge Trail in Arcata, Humboldt County, CA. Northwestern CA generally supports a decent population of Fishers but most of them are found inland, not along the coastal slope like these two were.

I had one run across our farm's orchard in broad daylight. Seemed to be heading toward a nearby marshy area.

Location: Twin Valley

I seen one run right through my front yard at about 7 AM. I live about a mile north of the Dam in Twin Valley. It was very plump and running towards the turkey farm. I noticed that I don't have rabbits running all over the place anymore like I used to have. And there was a porcupine spotted in my tree last fall and I sure hope he got it. I also noticed that I did not have one mouse in my house this year or my Barn Bldg. and I didn't put out any Poison only traps and only caught one mouse in a trap last fall. And it seems the squirrels all disappeared also, which is a good thing because they were getting out of hand. I don't have any pets but lots of deer hang out in my yard and wild turkeys were hanging out here last fall but maybe the Fisher had a good Thanksgiving...he looked really fat. I will try to get a picture of him tomorrow morning if he comes back.

Location: I filmed and photographed this fisher a few years or so back in the woods along the Wild Rice River in Norman Co. Mn. They do exist there today as I have seen tracks in the snow and occasional glimpse near a water hole in the woods in summer since.

It seemed curious about me and only got anxious when it wanted to come down out of the tree. I was below and it got a little nervous and started making these little chuckling sounds so I backed away and it came down the back of the tree peeking around keeping an eye on me and then scampered off away into the woods. I did not seem threatening at all.
