Sorry for the subject matter, Guys, but there is some critter leaving these piles all over my yard and I don't know for sure whar itis. Can anyone shed some light on it and help me identify the culprit? We have fox, weasel, fishers, coyotes, skunks, bears, deer, bob cats, lynx, raccoons, possums, moose, etc so I'm not sure. I know which ones it's definitely not, by the way.

Around here that looks like 'coon scat, except the seeds would be flattened and look like big pumpkin seeds--from persimmons.

I agree, probably coon.
