Herring Gull 1cy (argentatus), December 01 2000, Westkapelle, the Netherlands (51.33N 03.25E). Picture Pim Wolf.

A rather odd individual, with some argentatus features, as the elongated head 'snout' with the sloping forehead and the elongated rear end when perched. Most of the upper scapulars have been replaced for second generation feathers. The under-parts are relatively dark and chequered. The far outer greater coverts are almost completely dark. The basal half of the bill already turns paler. The centres of the tertials are extensive dark and reach all the way to the edge. The greater coverts are relatively dark as well, with a variegated pattern and extensive dark bases in the outer greater coverts. The outermost greater coverts are almost completely dark.
