I went to retrieve my trail cam pics today ( Saturday-6/13/09) and came across this picture of this certain critter. I myself think it's a groundhog. After a couple of my hunting buddies saw the picture they had different oppinions. One friend think's it a beaver, one friend thinks it's a fisher and yet another friend seems to think it's a very large musk rat.
What do you guys think it is?

def not a muskrat as muskrats have thin tail like a rat or possum-

Tail does not look quite wide enough for a beaver, and the tail on that thing has hair

I don't think it looks like a fisher at all (which looks more like a mink or marten).

Doesn't look a groundhog either- face looks wrong- I'm stumped.

dang thing looks like a wombat to me, but it would have to be someones pet that escaped- I think they are native to OZ?

I think it's a groundhog.

Ground Hog mixed w/ a beaver??????????

Whistle pig for sure.

Believe me jeffb it looks nothing like wombat,and yes wombats are native to australia.

where is this pic taken ? maybe that will help to figure what it is
Maybe a fisher cat?

No question, ground hog.

Looks like a groundhog/woodchuck to me as well..
