We estimated the allowable annual take of four gull species in the U.S. portion of the Atlantic Flyway to help meet human safety and resource management goals. Gulls can pose a serious threat to aviation, negatively impact other colonial-nesting migratory bird species, and conflict with other human activities. We calculated an annual mortality limit (potential take limit or PTL) for great black-backed ( Larus marinus ), herring ( L. argentatus ), ring-billed ( L. delawarensis ), and laughing gulls ( Leucophaeus atricilla ). To inform the PTL model we estimated an intrinsic population growth rate ( [[EQUATION]] ) for each species by combining allometric models with life-table models. The herring gull was the only species with comprehensive demographic data. Population sizes used in estimating PTL varied greatly among the 4 species but estimates of [[EQUATION]] were similar (range 0.118 to 0.197). Annual PTL among the 4 gull species was: 7,963 for herring; 2,081 for great black-backed; 15,039 for laughing; and 14,826 for ring-billed. Using average annual take 2012–2017 as a guide for future expected take, overharvest appears unlikely for great black-backed and laughing gull, slightly more likely for ring-billed gull, and likely in some years for herring gull.
