Stay still, keep your head down, and don't gawk.
"One important factor for everybody in the blind is to keep perfectly still—no movement until the shot is called. People in your group shouldn't be looking up at the geese. To be on the safe side, I think it's even better when everyone wears a face mask. One of the golden rules is that if you can see the geese, they can see you better; so keep still and don't move. I promise you that this simple bit of discipline in the blind will help you put more geese in your decoy spread."
