In trying to learn about the taxonomic status of the gull in question, I referred to "Waterbird Populations Estimates III", in which, Larus argentatus, the Herring Gull, is divided into several populations, including vega and mongolicus. The following information extracted from the publication may be of interest to readers.   Larus argentatus vegae   Breeding range - Taymyr to Chukotka & Anadyr, NE China Population estimate - unknown Core non-breeding range - W Pacific S to Japan, Korea, Taiwan, and S China Note: Possibly merits full specific status. Includes weakly defined birulai from W Taymyr to New Siberian Islands.   Larus argentatus mongolicus   Breeding range - SE Altai & L Baykal to Mongolia   Core non-breeding range - China & India   Population estimate - 57,000-66,000   Note: Very close to Larus (argentatus) vegae; maybe best treated as subspecies of vegae, if vegae split from argentatus. Yésou (2001) estimated the population at 19,000-22,000.     References: Yésou, P. 2001. Phenotypic variations and systematics of Mongolian Gull. Dutch Birding 23: 65-82. Wetlands International. 2002.
