Frigate or Man-o'-war Birds are well known to seamen from their remarkably powerful flight, and from the use they make of their speed in pursuing Gannets, Gulls, and Terns in order to rob them of their prey. The Frigate-birds live by piracy in tropical seas, just as the Skuas do in colder latitudes; but the species of Frogata do not confine themselves to fish taken by other birds : they often capture flying-fishes, cuttle-fishes, crabs, or even young turtles.
