Hard to say without seeing the mount.
I know a guy who used an old corner pole & braces from a barbed wire fence that hadn't been functional in a long time to mount his bird on. Both the bird & fence section came from his lease.
I know another guy who cut a section of a tree that runs floor to ceiling and he has a couple of birds mounted on branches of the tree. One is resting and the other is in strut. It sits in a corner of his hunting cabin & it looks pretty good. It takes up a bit of space, but it is unique. I'll see if I can find pictures.
