Status This large wading bird is endangered.

[edit] Taxonomy

This is a monotypic species[1].

[edit] Habitat

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

[edit] Behaviour

[edit] Diet

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

[edit] 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.
