Table 3. U.S. sites that host >1,000 Sanderlings during spring migration, and were surveyed by the International Shorebird Survey (ISS) for at least 5 years (during 1978–2005) 1 . Important sites that host at least 5,000 Sanderlings are indicated in bold.

Delaware Bay is known to be critically important to the Sanderling in spring (non-ISS data confirm this). a Count Category: Category indicates typical maximum count values of Sanderling during spring migration at that site (I = hundreds of Sanderlings; II = 1,000–5,000; III = 5,001–10,000; IV = 10,001– 20,000; V = >20,000). When values fell within several count categories, all categories were indicated. b Survey Period: Decade during which ISS counts were made (70 = 1970s, 80 = 1980s; 90 = 1990s; 00 = 2000s). Asterisks indicate the survey period (decade) during which the highest count category was reported. c Years: Number of years of spring ISS surveys (between 1978–2005).
