Report to the State of Delaware, Coastal Programs, pursuant to National Oceanic and Atmospheric Administration Award NA170Z1117. The population of Sanderlings Calidris alba along the East Atlantic flyway has grown considerably during the last decades. Perhaps reflecting this augmented population size, increasing numbers of Sanderling have been reported to stage in the Estimates of spring migration survival rates, stopover duration, and (Niles et al 2010a), the Atlantic Flyway Shorebird Business Strategy (Winn et al. 2013) Red Knots Calidris canutus in Delaware Bay 2002.
