... The middle station is positioned sort of behind the slope of a rolling hill, and consequently, it's not possible to see the full gunner/thrower bodies. It's also difficult to see the bird down, or actually picked up, depending where it falls. The judges are making sure the bird falls on a ledge out there, and when it doesn't, they call a no-bird. Because of the varying terrain, the left flyer often falls behind a slope as well and when this happens you don't see that bird picked up.
