Genus Calonectris
Cory's Shearwater - This species breeds on islands and cliffs in the Mediterranean, with the odd outpost on the Atlantic coast of Iberia. The nest is on open ground or among rocks or less often in a burrow where one white egg is laid, and is visited at night to minimise predation from large gulls. In late summer and autumn, most birds migrate into the Atlantic as far north as the south-western coasts of Great Britain and Ireland. They return to the Mediterranean in February. The biggest colony is located in Savage Islands, Madeira.
Cape Verde Shearwater - The Cape Verde Shearwater was originally described in 1883 by Émile Oustalet as a full species. It was later lumped as a subspecies of Cory's Shearwater but has since been separated again, by Cornelis Hazevoet in 1995, as a distinct species.
White-faced Shearwater - This species is pelagic, but also occurs in inshore waters. It occurs in the Pacific Ocean, nesting in Japan and many of its offshore islands. After breeding, the Streaked Shearwater will migrate toward southern Australia. It has been reported well off the west coast of the United States.
