(2 images) Herring Gull 3cy (argenteus), February 04 2002, IJmuiden, the Netherlands (52.27N-04.33E).
A typical argenteus
with the
mantle and scapulars adult-like plain grey. The brown second generation primaries
lack a mirror on P10. The second generation tail has a broad dark
tail-band.
The
new scapulars are uniform grey without any old brownish feathers left,
creating a clear "grey saddle", contrasting with the
wing-coverts.
This individual has moulted none of the wing-coverts to third
generation feathers in the partial autumn moult in the right wing.
However, in the left wing, the fifth greater covert is obviously fresher.
