They have a black and white body, pink webbed feet, blue eyes, dark brown bill, and a yellowish-orange nasal knob. The breeding season occurs around October-November. During the breeding season, every bird builds its nest in colonies about 9.8-65.6 ft (3-20 m) away from the high tide line.

The nest is made of feathers, shells, sticks, and aquatic algae. These birds feed on fish, snails, squids, sea slugs, algae, and more.
