It took everything not in the box! I almost didn’t know it was there but opened the box to check the trap/bait. Weasel and birds usually leave them more skeletonized in my experience but last year was the first time I set for marten. As good as marten are at cleaning up a carcass I figure it was eaten by a marten. I think that without good snow cover they are having a harder time than usual staying warm and getting the voles they would normally be eating.
