Over the years, I've seen pictures of bucks with all sorts of paraphernalia tangled in their racks; tree branches and limbs, barbed (and other) wire, even the head of another buck! The latter was a documented case, by the way; a hunter shot a buck that had apparently locked antlers with another deer, which had died. Somehow the live buck had been able to twist the dead buck's head off the carcass and escape. The operating theory was that coyotes had eaten through much of the neck. Why the live buck was ignored by the coyotes is a mystery.
