We were fortunate enough to arrive at the scene where a large group of loons had pushed a giant school of shad to the surface and the terns set on to it by the hundreds. At one point we were only about thirty feet or so away. It was truly an awesome sight to behold. I shot about twenty seconds of video and snapped a few shots.
