If he ship's superstructue is there then the birds are probably getting lifting off that at well - another free ride. I was thinking about skuas and terns diving - I suppose a albatross hitting the water would make a good thump !
In any case that feathered wing and its control/feedback systems is the most efficient yet designed.
