Large breeding colonies exist on islands in the eastern Atlantic, especially on Madeira and the Azores, where 85 % of the world\u2019s population breed. In these areas, the Cory\u2019s Shearwater is one of the most common breeding birds. Adult birds spend all day foraging and only feed their young at dusk and during the night to protect them from predators. The species\u2019 wintering grounds are in the southern Atlantic, probably mainly off the coast of South America."}
