Sooty Shearwaters feed on a wide range of marine fauna found in deep ocean waters, such as squid, fish and crustaceans. They mostly catch their prey by diving either from the sea surface or from 3 to 5 m above it, but usually from less than 1 m. They propel themselves under the water by slowly flapping their wings, and can dive to about 2 m, and stay submerged for up to 12 seconds.
The Sooty Shearwater nests on offshore islands, but in New Zealand sometimes on mainland headlands. It nests in a burrow or rock crevice on slopes, ridges or cliff tops. It prefers herbfields, tussock or forest and avoids water logged or shallow soils and dense vegetation. Its burrow may be winding in friable soils but is otherwise straight. The nesting chamber is at the burrow's end and the nest is roughly consructed of materials such as leaves, twigs, grass and seedlings.
Eggs are incubated by both parents for up to 16 days at a time. The sitting bird fasts throuhout its time on the nest. As the chicks grow the interval between feeds increases and has been recorded as 25 days between feeds. On Macquarie Island tussock areas grazed by rabbits have fewer burrows than ungrazed areas.
The former colony on Tasman Island, Tasmania, was probably affected by development of gardens, sheep grazing or feral cats. Where can I see them? What's being done to help them? How can I help?
