Herring Gull (argentatus & argenteus)

(last update: February 11, 2013)

Herring Gull argentatus KH89 January - September 2010, October 2011 & March 2015, the Netherlands & France.

Russian bird with on the left tarsus a white colour-ring KH89 and a metal ring Moskwa ES-14 783. It was born 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. The exact data: ringed on July 15 2009 on Farvaternaya Island - Severnoe lesnichestvo, Kandalaksha Bay in the White Sea (67.05N,32.29E).

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.

This is a strong powerful argentatus with only the upper scapulars replaced for 2nd gen feathers as 2cy January. The scapulars show wear in the white notched fringes but the coverts and tertials appear remarkable fresh considering it's already late January. Note the rather dark, clay-brown tone of the plumage, unlike the paler, washed-out brown of first winter Dutch argenteus.
