Bull moose casts a wary eye at his competition

With only a couple of weeks to go until the rut, bull moose are preparing for the annual competition for the right to mate with nearby females.  Here, a large bull stops eating to look behind him, keeping close watch on another male that was walking by.  

The tension this past Sunday at Brainard Lake in Arapaho National Forest was palatable and fascinating to witness.  Adding drama is the bloody velvet hanging from the moose’s antlers.
