This fellow is completely preoccupied by the enticing scent of three does; and p/o'd about another buck who is guarding them. He was about 20 metres from the truck and completely oblivious to me. His facial expression is called flehmen; he is using a sensory organ in the front of his mouth to detect the pheromones of a doe in heat.
The prior posting from me is an attempt to get the fight between the two bucks. However once the does and other buck saw me on foot everyone took off into the aspens. Man in truck; no problem. Man on foot pointing object; big problem
