photo 7624: Yellow-legged
Gull michahellis adult, August 11 2003, Le Portel, France
(50.44N,
01.35E).
P9-P10 still old, P5 fully grown. P6 slightly
shorter than P5. Note the black sub-terminal band on P4. Slender bill and small size and lack of a mirror on P10 could indicate
female. The old lesser coverts and central greater show some brown wash, but plain grey greater
primary coverts advocate full adultness. Note the small black spot on the lower
mandible.
