Have you ever seen a fight between a mule deer and whitetail?
An old whitetail and a young mule deer have a showdown in Montana. It's a bit odd for a whitetail and mule deer to fight, but stranger things have happened.
Watch the two sub species fight for their stomping ground.
Before watching this, I would assume the mule deer would be the one pushing away the whitetail. However, since the whitetail appeared to be larger and older it made quick work of the muley.
If the fight was a mature mule deer versus a mature whitetail, the mule deer would win in most cases.
This little battle took place during the rut. The rut causes bucks' testosterone to peak and provokes more aggressive behavior like the footage above.
