A seabird of tropical and subtropical oceans that nests in rocky crevices on remote islands.
Adults are white with a bold black mask, a colorful bill, and long tail streamers. Juveniles lack the long streamers and bright bill and have dark bars above.
It feeds mainly on small fish, especially flying fish, and squid, often catching them in plunge dives. It nests in caves, cliff holes, and other rocky crevices on remote islands.
