Great Shearwater Ardenna gravis

Sections

Breeding

They form large colonies in breeding season. Both parents incubate the eggs. The visits to the nests are made at night to avoid predation by gulls.

The nest is placed in a burrow in grassy hill. They lay one white egg. Incubation takes about 55 days.
