The video, filmed Wednesday from a Blue River resident's deck, shows a bull moose wandering around the property close to the home.

"I typically have a moose family roaming my property. I was on my deck and saw a mother her baby and a bull in my backyard eating willow tree leaves," the filmer wrote. "A few minutes later, a larger bull approached the area where the other bull was and the fight ensued. It was very exciting! I thought they were going to damage my deck, but luckily they didn't. The larger bull won and the smaller bull retreated and left."
