Great frigate bird (Fregata minor) mating ritual on North Seymour Island. The male inflates a red pouch at his throat to attract a female. Frigate birds have the largest ratio of wing span to body mass, thought to aid them in remaining aloft for long periods above the sea as they hunt flying fish, squid, and other fish.
This downy chick is about 3 weeks old. Parents take turns hunting and caring for their chick for a period of 4-6 months, the longest period of parental care for any bird.
Parents feed their young by regurgitating fish. We watched this mother and chick for several minutes as other frigate birds swooped in, hoping to steal free food, before the mother opened her beak to feed her chick.
