Herring Gull 2cy (argentatus), August 07 2002, Tampere, Finland (61.31N,23.43E).

A very brown "washed out" 2cy argentatus from Finland, resembling this bird from Poland. 
The complete moult is almost finished with most wing-coverts and the inner primaries moulted to second generation. The outermost primaries P9-P10 are still juvenile and P1-P6 are fully grown second generation flight-feathers. The innermost secondaries are still juvenile. All tail-feathers are second generation now, with the outer rectrices still growing.
The tertials and most of the wing-coverts are replaced for second generation feathers. The last moulted wing-coverts are the outer lesser coverts. These feathers have a neat fringe. All juvenile scapulars have been replaced for second generation feathers, including the scapulars in the lowest row. The upper scapulars and mantle were replaced long ago and the old second generation feathers look abraded. A few lower upper scapulars are missing.

By August, the neat fringes of the first moulted wing-coverts (upper tertials, inner greater coverts and median coverts) start to wear away. On average, 2cy argentatus is more contrastingly patterned than same aged 2cy argenteus, especially regarding the pattern on the inner and central greater coverts and the white belly and flanks. However, some argentatus are distinct "washed out" brown like this individual or show the common vermiculated pattern of 2cy argenteus. 
The last moulted coverts are the central greater coverts and outer lesser coverts, replaced by mid-August. From mid-August onwards, 2cy argentatus start the partial autumn moult, starting again to drop the upper tertial and inner greater and median coverts.
