Two young elk bulls square off on the shores of Lake Estes in Estes Park, Colorado.
While these two are young enough that they most likely couldn’t defend a harem from more seasoned competitors, they still are willing to practice future battles with each other. They sparred back and forth for 10 minutes or so with the slightly larger one (left) emerging the victor and poking the smaller one in the butt to chase him off.
Up in Rocky Mountain National Park we saw some more seasoned competitors challenge each other but only from a distance.
