					Found offshore, in 15 to 25°C waters (Ref. 356).  Forms breeding colonies on oceanic islands.  Does not typically trail ships (Ref. 91362).   A  less specialized kleptoparasite with varied feeding behavior, including surface-seizing.  Mimics skuas to successfully kleptoparasitize other seabirds; typically attacks from a lateral plane to frighten its target  with sudden aerobatic acceleration achieved  by continuous wing flapping.   (Ref. 89445).
