Large prehistoric looking bird. Very shy; avoid areas heavily used by people.

Nest exclusively on coasts (sheltered or surf beaches) and offshore islands or estuaries. Avoid cliffy areas and large stands of mangroves.

Lay a single egg, in the open or by cover. Hatch after a month and adults are very reluctant to leave the nest. They can charge at intruders.

Chicks takes up to 11 weeks to fledge.
