Long‐Term Population Trends and Spatial Redistribution of Shorebirds at a Critical Migratory Stopover
ABSTRACT Understanding population change in migratory shorebirds is critical for conservation, particularly at key stopover sites where individuals concentrate during migration. Using nearly four decades of standardized peak aerial count data (1986–2025), we examined long‐term population dynamics of four abundant shorebird species at the Delaware Bay spring stopover: Red Knots ( Calidris canutus rufa ), Ruddy Turnstones ( Arenaria interpres ), Sanderlings ( Calidris alba ), and Semipalmated Sandpipers ( Calidris pu …
