photo 11: Yellow-legged Gull michahellis 2cy, August 25 2000, Le Portel / Boulogne-sur-Mer, NW France.
Another
pretty straightforward michahellis, easily identified by the bold
pattern on the coverts, the relatively dark grey fresh scapulars, the
salmon pink legs, the pitch black centres of the tertials and the advanced
moult stage in the primaries by the end of August: P8 is fully grown and
P9 has to grow just a few inches. The two upper tertials have been shed
and are the last to be replaced. In the greater coverts, only the #2 has
to grow a little and the other feathers show fresh white tips. The moult
strategy in the median coverts is rather complex with two moult gaps: #1-6
are fully grown, #7 is missing, #8-9 are fully grown, #10-12 are missing,
#13 is present. There are no feathers missing in the lesser coverts. In
the tail, most feathers have been replaced but some still have to grown a
few inches.
