This is one fight you do NOT want to break up. Tawny Tersmette was heading into Peter Lougheed Provincial Park in Alberta for an early morning hike when she saw two large bulls going head-to-head on the side of the road, she told CBC. Filming from her car, she captured this remarkable footage of the bulls engaged in full combat. The province's moose rutting season usually runs from mid-September to mid-October.
Moose bulls, while usually solitary, can become aggressive with one another when a female moose's calls bring them into competition.
