Chatham Island Oystercatcher

Haematopus chathamensis, the tōrea, is an endemic shorebird confined to the Chatham Islands. It differs from mainland pied oystercatchers through its island range, heavier proportions and diagnostic plumage details. It is black above and white below with a stout orange-red bill and pink legs. The white breast boundary and wing pattern assist expert identification.

It breeds only around rocky shores and beaches of the Chatham Islands. Pairs require undisturbed feeding and nesting coastline above normal tides. It eats molluscs, worms and crustaceans from rocks, sand and tidal flats. Eggs lie in shallow scrapes vulnerable to storms and introduced predators.

The New Zealand classification is Nationally Critical. Main Chatham Island coastlines offer guided opportunities, but access and nesting-site sensitivity require local advice.
