Behavior
Eggs
One. Creamy white, spotted with brown. Incubation (by both sexes) averages 65-66 days.
Young
For about 18-20 days after hatching, one parent broods and guards the nestling while other forages for food, taking turns every 1 or 2 days. Young is fed by regurgitation, by both parents, until it leaves the nest. Period from hatching to departure from island is about 140-150 days.
Feeding Behavior
Forages while swimming by seizing items at surface, up-ending to reach underwater, or diving short distances underwater with wings partly spread. Feeds mostly early morning and evening.
Diet
Fish, squid, crustaceans. Around Hawaii, feeds heavily on the eggs of flying fish. Also eats many squid, adult fish including flying fish, and crustaceans. Will scavenge carrion or refuse at sea.
Nesting
First breeds at age 5 years or older. Courtship "dance" of pairs is complex, includes many ritualized movements including bowing head, mutual preening, swinging head from side to side, pointing bill straight up while calling. Nest: Preferred nest sites are on higher parts of open sandy beaches. Nest is a simple, shallow depression, with a slightly built-up rim.
