Info

Clatsop Beach reportedly hosted about 80,000 Sanderlings between 23 July and 6 August 1983 (Contreras 2003). Oregon Dunes National Recreation Area supported >18,000 Sanderlings during 1993 (Platt and Goggans 1993). Mexico, Central and South America Baja California, Mexico: Counts at two sites, *Guerrero Negro/Ojo de Liebre and to a lesser extent *Laguna San Ignacio, showed an influx of hundred/s of Sanderlings during fall (August 2006) and spring (March 2007/April 2008) migrations, temporarily increasing winter numbers there (R. Carmona, unpubl. data). Costa Rica: Two sites are listed as each hosting 5,000 Sanderlings during migration: Pacuare, coastal wetlands and Migratory Bird Corridor, and Cahuita, Gandoca-Manzanillo, and Migratory Bird Corridor (World Bird Data Base 2009). * Lagoa do Peixe, Brazil: Spring migration: This coastal lagoon is a major staging site for Sanderlings on the Atlantic coast of South America. Counts reported in the 1980s regularly exceeded 6,000 Sanderlings in spring, just prior to their departure for North America (Morrison and Ross 1989). Rios Sergipe and Vaza-Barris, Brazil: The lower reaches of these rivers form a system of freshwater wetlands grading into mangrove swamps. The mangroves shelter thousands of migrating shorebirds, especially Sanderlings (DeLuca et al. 2006). Iguape-Cananeia Estuary, Brazil: One of the largest estuaries in southeast Brazil, this system of channels, islands, and mudflats are isolated from the sea by two islands, Ilha Comprida and Ilha do Cardoso. Ilha Comprida is an important stopover area for migrating shorebirds, especially Sanderlings (DeLuca et al. 2006; number of Sanderlings not specified). La Coronilla-Barra del Chuy, Uruguay: This site (on the central coast of Uruguay) reportedly hosts 3,000 Sanderlings during migration (World Bird Database 2009).

NONBREEDING (WINTERING) SITES Although the Sanderling is the most widespread maritime shorebird in the Western Hemisphere during the nonbreeding season, Sanderlings are fairly dispersed and numbers tend to be small locally throughout most of their winter range (e.g., coastal Argentina; Blanco et al. 2006). Sanderlings winter along most beaches in the temperate and tropical Americas, spanning over 100 o in latitude, from 50 o N on the Pacific Coast (southern British Colombia) and 43°N on the Atlantic Coast (southern Maine) south to 50°S (southern Chile and southern Argentina) (Myers et al. 1985, Castro and Myers 1987, Myers et al. 1990). However, most Sanderlings winter in one of three regions: the Pacific coasts of Peru and northern Chile (where high densities in areas not listed below reach 25–60 birds/km); the U.S. Pacific coast (Washington to southern California); and the southeast Atlantic coast of Brazil (Morrison 1984, Myers et al. 1985, Morrison and Ross 1989). Atlantic and Gulf Coasts (United States) The sites listed below were surveyed by the ISS between 1972–2005, and hosted several thousand wintering Sanderlings during that period. Other ISS-surveyed sites with winter estimates of >1,000 Sanderlings occur in Florida, Georgia, Maine, Maryland, Massachusetts, North Carolina, and Virginia (See Table 5). Florida coast: Sanibel Island reported several thousand Sanderlings in the 1990s, with winter counts in the hundreds in the 1970s and ’80s (ISS data). Massachusetts beaches: Five hundred to several thousand Sanderlings winter in South Beach, Chatham, as reported in the 1990s (ISS data). New Jersey beaches: Brigantine Beach (in the 1970s) and Wildwood (in the 2000s) each reported >5,000 Sanderlings during winter months (ISS data). North Carolina: Pea Island NWR (during1970s) and Clam Shoal/Bird Island (during 2000s) hosted >1,000 Sanderlings during winters (ISS data).
