Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) BREEDS: southern California (casually, since 1979), southern Sonora, southeastern New Mexico, northern Texas, central Oklahoma, central Kansas, southwestern Kentucky, southern Georgia, and Atlantic coast north to Maine, south along both coasts of Mexico and Middle America, to the West Indies and South America (Colombia, Venezuela, and Guianas west of Andes to central Peru and east of Andes to eastern Peru, central Brazil, and Uruguay; sometimes in central Minnesota. See Spendelow and Patton (1988) for information on distribution and abundance of coastal U.S. breeding populations. NORTHERN WINTER: north to southern Baja California, southern Sonora, Gulf Coast, and Virginia, south through most of the breeding range. In the U.S., the highest winter densities occur in southern Louisiana bayous, around the mouth of the Mississippi River, especially the Delta NWR, and to a much lesser extent in Florida (Root 1988). Wanders irregularly outside usual range, especially after breeding. Accidental or casual in Hawaii.
