... It is outside of the point of this post since the OP is talking about decoyed ducks, but try stalking mallards (or wood ducks as in the OP's example) and getting a shot off without them knowing you're there. I believe that is WAY tougher than shooting them as they have their wings cupped. To my thinking, sneaking up on resting birds is way more of a challenge than blasting them out of the air, which is just shooting if you didn't do the calling or decoy placement.
