Gull C033V3cy (argentatus),
January 15 2004, Lubna rubbish
dump, Poland (52°02'N 21°08'E).
A typical argentatus
ringed as pullus, July 01 2001 at Ylöjärvi, Häme, Finland (61°33'N
). The brown second generation primaries
lack a mirror on P10. The second generation tail has a broad dark
new scapulars in northern argentatus may appear very second
generation-like, but this individual shows grey feathers with a clear
black shaft-streak. There are no uniform grey
feathers, and all wing-coverts are brownish with a clear anchor pattern. Some
grey scapulars appear abraded at the
fringes already, especially in the upper scapulars and the back.
This individual has moulted the tertials #1-2 and some wing-coverts in the
partial autumn moult as 2cy bird: median coverts #9-> and and some lower lesser coverts have been replaced. The
new feathers have fresh fringes and tips. The patterns are very similar to
the second generation feathers, although these new feathers are buffish-grey based.
