My guess is you don't bring any grouse to bag as the only thing you shoot is your mouth off...
That picture is from 10 days ago. I could have shot it in the tree instead of taking its picture, but it wouldn't be sportsmanlike. That matters to some. How you behave when nobody's watching says a lot about your character.
I shoot grouse because they are delicious. I will kill them with a rifle, shotgun, a rock, a stick or my bare hands if I could catch them. Your definition of "sportsmanlike" is your own,what makes you the authority? How you behave when your safely hidden behind a keyboard says a lot about your character.
