Cool Facts

  • In migration, the Western Sandpiper stages in huge, spectacular flocks, particularly along the Pacific coast from San Francisco Bay to the Copper River Delta in Alaska. Estimates suggest that as many as 6,500,000 individuals pass through the Copper River Delta during just a few weeks each spring.
  • The oldest recorded Western Sandpiper was at least 9 years, 2 months, when it was recaptured and rereleased during banding operations in Kansas.
