Year-specific population size and composition estimated from an integrated population model fit to Piping Plover data from Fire Island and Westhampton Island, New York, 2013–2018. Values presented are the mean ± standard deviation. N = number of individuals, Imm = immigrants, and tot = total number of individuals in the breeding population. SY indicates birds in their first breeding season and ASY represents after second-year birds, ≥1 yr post-hatch. Stage nomenclature is associated with age of breeding individuals.
