Photo 8900: Yellow-legged Gull michahellis 2cy, January 05 2002, Etaples, NW France (50.44N,1.35E).

A 2cy michahellis with many moulted wing-coverts and tertials. Tertials #1-4 are second generation feathers with a broad white fringe on the last moulted central tertials. Greater coverts #1-4 are second generation as well, #5 is still juvenile, #6-7 are fresh second generation and show a greyish base. The outer greater coverts are still juvenile. Median coverts #1-3 are old second generation coverts, #4 is fresher, #5-8 are old second generation, #9-10 are newer, #11 is still juvenile, #12 is a fresh second generation feather and #13-14 are juvenile. The lower lesser coverts #1-5 are second generation, #6 is juvenile, #7-10 are second generation and the outer lower lessers are juvenile. Already about 80% of the lesser coverts has been replaced for second generation feathers. All feathers are present; there is no active moult in progress in the wing-coverts and tertials.
One lower scapular is missing, the other feathers in the lowest scapulars are fresh with a grey base on the last replaced second generation feathers. Two upper scapulars are missing and one feathers is growing; again there is active moult in this feather tract. Already, one lower upper scapular is a fully grown grey- based third generation feather.
The head shows a dark patch around the eye and a boldly streaked neck-collar. The bill is all dark.
