Common Gull - WHITE [EZ77] / black
Edit: confirmed as subspecies Larus canus heinei.
Russian Common gull (Larus canus heinei), adult
Zoetermeer, Noordhovenseplas, The Netherlands, January 8, 2010. W[EZ77] (Arnhem 3690757). Adult Common Gull in full winter (basic) plumage after being measured and ringed and identified as a Russian Common Gull. Note the fuller head and slightly heavier bill. The color of the grey mantle and wing feathers is also slightly darker, an aspect best viewed when compared next to a regular Common Gull. See also this image of a sighting of this individual in December 2010.
Russische Stormmeeuw (Larus canus heinei), adult
Noordhovenseplas, Zoetermeer, 8 januari 2010. W[EZ77] (Arnhem 3690757). Adulte Russische Stormmeeuw in volledig winterkleed. Op basis van gedane metingen is dit individu geidentificeerd als Russische Stormmeeuw. Karakteristieken zijn de hoekerige kop, iets bredere snavel en donkere mantel- en vleugelveren (dit is het best te zien door het direkt met een westerse Stormmeeuw te vergelijken).
