Yellow-legged Gull michahellis sub-adult,
October 01 2001, Le Portel,
France (50.43N,01.37E).
Primary P7
is fully grown, P8 is at the tip of P7 and P9 is at the tip of P3 (just
visible). All old primaries have been shed. Note the rather pale yellow base of
the bill and the extensive black markings on the bill, indicative for
sub-adults.
