Fellow outdoors writer Chris Niskanen at the St. Paul Pioneer Press posted some good video of two bucks fighting just days before the Minnesota deer season in the back yard of a St. Paul man. Two videos are posted here. Be sure to crank the sound up as you watch. The sound of those antlers clashing is pretty amazing.
Bucks fight to exert dominance over other bucks and gain breeding privileges with does in the area. Like frogs calling all night in the spring and the courtship demonstrations of loons in early summer, this buck encounter reminds us that animals go to great lengths to perpetuate their species.
