3cy (argenteus), February
04 2002, IJmuiden, the Netherlands (52.27N-04.33E).
A typical argenteus
ringed in the
Netherlands: Arnhem Ringstation 5.361.1??,
probably a local bird and ringed in 2000 at IJmuiden, the Netherlands.
The brown second generation primaries
lack a mirror on P10. The second generation tail has a broad dark
new scapulars are more
or less uniform grey with just a few patterned brownish feathers left in
the rear upper and lower scapulars. Some grey scapulars appear abraded at the
fringes already, especially in the upper scapulars.
This Dutch individual has moulted tertials and wing-coverts to third
generation feathers in the partial autumn moult: the three upper tertials
have been replaced, greater coverts #1-3 have been replaced, all median coverts and
four lower lesser coverts have been replaced. The
new feathers have fresh fringes and tips. The patterns is very similar to
the second generation feathers, although most are typically grey-based
faint sub-terminal markings and a pronounced shaft streak.
