Recent Research: Trends in nonbreeding shorebirds along the Pacific Americas Flyway. Published in Oxford Academic. Population trends for shorebirds that spend the nonbreeding period of their annual cycle along the Pacific Americas Flyway are largely unknown. However, localized studies within the Pacific Flyway and analyses from the Atlantic Flyway suggest many shorebird species may be declining in the Western Hemisphere. Herein, we present the first trends of nonbreeding shorebirds along the Pacific Americas Flyway based on a coordinated survey effort from across a large portion of the Flyway. Read more here.
