Sooty shearwaters at sea

Seabirds obtain all or most of their food from the sea. New Zealand has nearly a quarter of the world’s seabird species breeding on its mainland and offshore islands, and of these, 44% breed nowhere else in the world. The most abundant species is the sooty shearwater (muttonbird or tītī), with an estimated population of 20 million. About 4.5 million come to the tiny Snares Islands to breed each year (down from 7.5 million in the 1970s), as do many thousands of other seabirds.
