3CY COMMON GULL
Common Gull has a partial moult in spring. It starts in February and is completed by April, leaving birds in so-called "second summer" plumage. The head turns white, with only a few dark markings in some birds. The small primary tips wear off and the black areas turn paler, brownish.
From early summer to October, a complete
moult will bring birds in so-called "third
winter" or "adult winter" plumage.
The head is white with spots, most densely in the hind-neck. The
under-parts, tail-coverts and rump are white. The upper-parts are
medium grey, with broad white fringes on the tertials. The third
generation primaries and later the adult primaries have a clear-cut
black triangle on the outer-wing. Black sub-terminal markings run
down to P6 or P5. From P1-P9 the primaries show extensive white tips
and the two mirrors on P9 and P10 are obvious (there may even be a
small mirror on P8). The iris is brown, the bill is yellowish with a
faint black bill-band and the legs are yellowish, greenish or
greyish, often with a flesh-coloured hue.
