Larus fuscus fuscus in 2cy often returns with completely replaced primaries and secondaries. In 3cy, fuscus more often shows a clear division between fresh inner primaries and older outer primaries, the inner primaries often showing neat white tips and the outer primaries often second generation-like with rounded tips and paler bleached brown. The arrested moult in the primaries is often reflected in the secondaries and (to a less extend) in the tail-feathers as well. The older tail-feathers (often R5 is older) still show a broad dark sub-terminal band.
C5H8 was ringed as pullus in 2001, now in 3cy. The primary moult stage in this 3cy: P1-P6 3rd generation and P7-P10 old 2nd generation. The moult in the primaries is clearly suspended and simultaneously, there is no active moult in wing-coverts or tertials. The outer primaries are paler bleached brown and worn. Note the grey-tone of upper-parts in direct comparison with Ravens.
