Herring Gull KV79 2cy (argentatus), January - April 2007, Westkapelle, the Netherlands. Pictures Pim Wolf. 

Not at all a strong powerful 2cy argentatus with almost the complete juvenile plumage retained, as one would expect. Instead, a bird hardly distinguisable from local Dutch Herring Gulls, with about half of the scapulars replaced by mid-winter. Also, rather small in size, not unlike average local birds. In the last images, note the tappered, wedge-shaped tail-band, somewhat resembling michahellis, but with four extra black transversal lines on the outerweb of R6, unlike michahellis.

It hatched last summer along the coast of the White Sea in the Kandalaksha Nature Reserve (67.15N,32.30E), Murmansk District, Russia in a project of Vitaly Bianki; probably on Lunnaya Island, Kandalaksha Bay in the White Sea (67.05N,32.29E). Many thanks to Vitaly, who wrote a paper about the ring recoveries of his project, which can be order at the Bird Ringing Centre of Russia. If it is out of print, you can ask how to obtain this report in the Centre after mid-August 2002 by e-mail: ring@bird.msk.ru. Title: "Marking of Herring Gulls (Larus argentatus) with plastic rings." In this book you find ringing records from Russia and adjacent countries 1988-1999. The report is in Russia, with an English summary.

From this region, Kleinschmidt describes a large, very long-winged Larus argentatus major breeding from the SE Baltic towards the White Sea. It's a pale grey mantled and partly yellow-footed Herring Gull in adult plumage. The juvenile and 2cy plumage are not described. However, this bird strongly resembles the argentatus from Finnmark Scandinavia, entering the Netherlands by mid-winter.
