Yellow-legged Gull michahellis adult, August 10 2003, Etaples, France (50.44N, 01.35E).
Advanced michahellis regarding secondary
and rectrices moult. The lower tertials are moulted, creating a gap at the
innermost secondaries and in the mean time, secondary moult started at the
division of primaries and secondaries. S1-S2 are just visible. Primary moult is
just slightly advanced as well, as P1-P5 are already fully grown and P9-P10
left.
This advanced moult in remiges and rectrices, together with the full black
sub-terminal band on P4 might suggest sub-adultness, but the under-wing greater
primary coverts appear plain white, without any trace of black and the bill
completely lacks any black. Note the red
orbital ring, large red gonydeal spot, deep yellow iris without speckling and
deep yellow legs. P10 has a mirror on inner and outer-web.
