photo 9: Yellow-legged Gull michahellis 2cy, August 25 2000, Etaples / Boulogne-sur-Mer, NW France.
A
classical 2cy michahellis by the end of August. Most of the
scapulars are grey. The upper two tertials are missing, one of them is
growing. The greater coverts have all been replaced and the white fringe
at the tip of the last moulted feathers is obvious. On average, the
pattern in the greater coverts may be more well-defined, with bold barring
or notching, especially on the inner greater coverts. Here, the pattern on
the outer greater coverts is rather washed-out, with hardly visible
variegated densely barred pattern on the feathers. Such a pattern can be
found commonly in 2nd generation greater coverts of argenteus
Herring Gulls. The outer median coverts have been replaced most recently
and they appear much more adult-like than the other coverts, being grey
with a dark shaft streak. In the lesser coverts a few similar grey
feathers have been moulted in but most of them appear contrasting
patterned with pale fringes and a brownish centre. Primary moult score: P8
is fully grown. Note the basal half of the lower mandible which is pale
pinkish and the iris turning paler in August.
