Vega Gull

The Vega gull, East Siberian gull, or East Siberian herring gull is a large gull of the herring gull/lesser black-backed gull complex which breeds in Northeast Asia. Its classification is still controversial and uncertain. It is variously treated as a separate species, as a subspecies of the American herring gull or included with both the American herring gull and European herring gull in L. argentatus. The Mongolian gull Larus mongolicus was formerly regarded as a subspecies of Vega gull. It was described in 1887 from specimens collected on the 1878–1880 Vega Expedition on the Swedish ship SS Vega.
