The rut is getting close and even a few weeks ago when this picture was taken, the Moose bulls were establishing a pecking order.
Here, two go head to head leading up to a bit of pushing and shoving. Unfortunately, this was before the sun hit the valley floor so my pics of the action came out blurry due to the necessity of a slow shutter speed. Sigh.
These two big guys were part of a bachelor group of four, but, they were only the middle two in terms of size. There was another with them that was clearly the senior and dominant one of them all. Taken in Arapaho National Forest, Colorado.
