Photo 4281: Yellow-legged Gull michahellis 2cy, May 04 2001,
Etaples, NW
France (50.42N,1.34E).
A 2cy michahellis, probably male.
In the scapulars, 6-7 feathers are third generation grey-based feathers,
while the other scapulars barred second generation feathers. The recently
moulted scapulars show a blue-grey hue.
The rectrices and all the greater coverts are still juvenile. The upper
tertial is missing. In the median coverts, one central feather is second
generation; four inner lesser coverts are second generation as well.
Note the abraded tips of the juvenile
secondaries, visible beneath the greater coverts.
