photo 15: Yellow-legged Gull michahellis 2cy,
August 25 2000, Etaples / Boulogne-sur-Mer, NW France.
The
tail has been renewed completely, primary P8 is fully grown, P9 has to
grow a few inches and P10 is halfway it's final length. Except the
innermost secondaries which are still growing, all second generation
secondaries show a neat dark centre. Note the grey scapulars and the white
upper-tail coverts, contrasting with the broad tail-band. The second
generation inner primaries show a window, which is more obvious in 2cy
than it is in 1cy, but still not as well-defined as in argenteus
Herring Gull.
