Fall migration of Ross' Gull (Rhodostethia rosea) in Alaskan Chukchi and Beaufort seas: Final report

Ross’ Gulls (Rhodostethia rosea) are a major component of the pelagic avifauna of the Alaskan Chukchi and Beaufort seas in fall. Until recently, however, their distribution, abundance, and phenology of occurrence in Alaskan waters was poorly known. Since 1970, a combination of shipboard, aerial, and land-based surveys has revealed the major features of this species’ post-breeding movements in Alaska.
