2. Let some of them go.
Some birds aren't worth the risk of shooting at them. Cheney whirled around to take a quail that flushed behind him. To safely shoot a bird behind a line of hunters, you don't spin and shoot; you point your muzzle straight up in the air so as not to swing it past anyone else. You turn around. With the muzzle up, you look for other people, dogs, and trucks before you point the gun. I've done this safely a million times, but after the Cheney accident, I may let those birds go.
