The Chatham Island Oystercatcher is a black-and-white shorebird found only on the Chatham Islands. Pairs defend coastal territories throughout the year.
Adults have black-and-white plumage with a smudged border between the colours on the breast. Red eyes, an orange bill, and pink legs are also characteristic.
Pairs defend territories year-round on rocky or sandy coasts. They probe or pick through the substrate with their bills for molluscs and small crustaceans.
It nests in shallow sand or gravel scrapes or in depressions on rock. Both parents incubate the 1–3 eggs for about 29 days. Chicks can move as soon as their down is dry.
Alongside molluscs and small crustaceans, it eats polychaete worms, sea squirts, and anemones.
Juveniles have paler bare parts and a dark-tipped bill.
