Ecology and Life History

Migration

false - false - true - Makes long transequatorial migrations between breeding and nonbreeding ranges, though some birds may spend the nonbreeding period south of the equator. Migrates along Atlantic coast of U.S. May-June; to Canada Labrador, and southern Greenland July-late September. Moves eastward out to sea in late northern summer. Millions of migrants occur off U.S. Pacific coast in northern spring and summer (Briggs and Chu 1986). Sporatically common to abundant off Pacific coast of Costa Rica mainly May-October (Stiles and Skutch 1989).

H - >2,500,000 square km (greater than 1,000,000 square miles) - H - BREEDS: on islands off southeastern Australia, New Zealand, and southern South America (Wollaston and Deceit, probably also Huafo and Mocha, off Chile; off Tierra del Fuego; Falkland Islands). RANGES: at sea widely in Pacific and Atlantic Oceans; north to southern Bering Sea and Aleutian Islands in Pacific and to Labrador and Greenland in Atlantic; fairly common off east coast of North America, abundant off west coast (National Geographic Society 1983).
