This image from Saturday shows two bull moose squaring off in what was a relatively gentle test. Preparations for the rut in September / October? Possibly. Like elk, moose will become very aggressive during mating season. Any humans in the vicinity could find themselves attacked.
Taken at Brainard Lake in Arapaho National Forest, Colorado.
This guy was one of five at a spot in Arapaho National Forest west of Boulder, Colorado this morning. He was one of the smaller ones but also one of the more photogenic.
This is the first time I have this close to a bull moose and let me tell you, they are massive, impressive animals to say the least. Their sheer size is absolutely intimidating and nothing you want to mess with.
