Yikes. Are all those dead deer from THIS winter?
Judging by the relatively intact state of those carcasses, they don’t look like wolf kills to me. Coyotes could only bring down bucks that size under extraordinary circumstances.
What killed those deer?
Grouse
My guess is … EHD, Vehicles, Bad shots during season, or poachers. But thats just my guesses as a few were in water and a few were close to roads.
