421: Yellow-legged Gull michahellis 2cy, May 17 2002, Le Portel, NW
France (50.42N,1.34E).
A 2cy michahellis (so-called
"first summer" / first alternate) with some third generation
grey scapulars, which can be found in the lower upper scapulars. They are
plain grey with a pronounced dark shaft streak. The head is almost white,
but some michahellis may show streaking on the nape and around the
eye by May. This individual has shed most of the outer median and lower lesser
coverts. The upper tertials have been dropped as well.
