Status This large wading bird is endangered.

Taxonomy

This is a monotypic species[1].

Habitat

Open sandy and rocky beaches, exposed reefs, mangroves, and tidal sand or mudflats.

Behaviour

Diet

It is thought their diet consists almost entirely of crabs, with the addition of some other small crustaceans.

Breeding

They lay their single egg in a shallow scrape, above the tide line; on beaches, sandbanks islands are in mangroves. They will relay if the first attempt fails. Both adults defend the nest and care for the precocial young. They become independent at around 7-12 months.
