Start throwing them back, maybe whatever it is will stop.........LOL!
Have you considered setting up any trail cameras or tracking it in the winter snow?
Set up 5 trail cameras because I discovered they were Blacktail deer on my property. They’re not supposed to be there, about 60 miles away from their normal range. Anyway, all of the cameras were ripped off the trees, cases broken, straps broken when they were taken down and one of the cameras was never found again. Bears will chew on cameras if they find them, no chew marks just strange…
Also, it does leave tracks. One set of tracks actually has dermal ridges. Fingerprints! There’s do not have fingerprints, they have a soft pad just like a dog.
