Spinning-wing decoys are fairly common on the public fields where I hunt. For safety’s sake, everyone lines up on one side of the field, with their spinners out front and no one beyond. It is a fact that the more spinners in a field, the less effective each becomes, but a lone dove will sometimes decide that your decoy marks the eye of the storm and will pitch in, making for a deceptively difficult shot. A decoying dove floats down, making little dips along the way. You will miss if you try to track the dips or be too fine in your aim. Instead, keep the muzzle below the bird so you can see it, look at the beak, and shoot. If you don’t tend to handle that shot well, put your spinner to one side so it draws birds past you for short, easy crossing shots.
