Total Length: 35 to 38 cm; Wingspan: 73 to 76 cm (Ref. 8812). Found along the coast and continental shelf (Ref. 356). Exclusively marine. Breeds singly or in loose colonies, typically along cliffs (Ref. 91362). Breeding colonies may be found on tropical islands, along beaches and low sea cliffs. Heavily preyed on by rats (Ref. 84934). Exhibits dipping behavior (Ref. 356). Feeds mainly by plunge diving or by dipping the surface while hovering. Diet primarily consists of fish, especially five-horned cowfish, juvenile flyingfish, goatfish, herring, and dolphinfish, but also eats squid, crustaceans, mollusks and insects (marine and terrestrial) (Ref. 122680).
