The Tropic-birds, called by sailors Boatswain (Bosun) Birds, because, it is said, the long median tail-feathers recall the Boatswain's marling-spike, are truly oceanic, and are commonly seen at a distance from land, where they attract attention by their habit of flying up to ships, hovering round the masts, and sometimes resting on the masthead. They have a swift and elegant flight, and are often seen with their bills pointed downward, but: they turn their heads in various directions, sideways and even backward when flying. Their visits to ships appear due to curiosity, anything serves to attract them, and the firing of a gun will often bring them from a considerable distance. They feed on fish captured on the surface. They breed on oceanic islands, chiefly in holes of rocks, laying a single egg, pinkish-white in colour, mottled, spotted, and smeared with brownish purple.
