H - >2,500,000 square km (greater than 1,000,000 square miles) - H - BREEDS: western and northern Alaska, northern Yukon, northrn Mackenzie, Canadian arctic islands (except northernmost), and northern Labrador south to western Alaska, east-central Mackenzie, southeastern Keewatin, northeastern Manitoba, Southampton Island, northern Ontario, northern Quebec, and coastal Labrador. Nonbreeders often spend breeding season in coastal North America south to Gulf Coast, Panama. NORTHERN WINTER: Florida and Bahamas south to West Indies, Atlantic coast of South America (to Paraguay and southern Brazil), and Pacific coast from Guatemala south to northern Chile. Accidental in Hawaii. By far the largest numbers in winter occur on the northern coast of South America, centered on Suriname and the Guianas (Morrison and Ross 1989). Delaware Bay is the most important spring stopover in the eastern U.S. (Clark et al. 1993). The Bay of Fundy is an important staging area during fall migration and is used by perhaps 1-2 million individuals (up to 50-90% of the world population) (Mawhinney et al. 1993).
