The International Shorebird Survey (ISS) is the longest-running shorebird monitoring program in the Americas. Over 2,450 volunteers have surveyed nearly 70 million shorebirds at over 9,700 sites in 36 countries since 1974. Survey data have facilitated the identification of important areas for migratory shorebirds, supported the nomination of WHSRN sites, and been a reliable data set to assess shorebird population status and trends, used, for example, in the State of the Birds of North America reports.
