Sanderling Plan - Western Hemisphere Shorebird Reserve Network

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.

Exception is Padre Island National Seashore, which hosts many Sanderlings but was surveyed one year.
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).
