I can see several options to that picture.

Option 1
Bird charges hunter. Good thing you are there to take him down with your double rifle.

Option 2
Stop or I will shoot....... again.

Option 3
Do not shoot until you see the whites of their eyes does not work well on birds.

Option 4
You bet the wife a pound that you have the high bird count you have to get them anyway you can.

Option 5
Wife shoots them out of the air. I shoot them on the ground. How many birds do you see charging like this. See. She gets more chances because she shoots all of those flying birds.
