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.
3cy fuscus often have some black markings on the bill, which is otherwise
much adult-like, with a clear red gonydeal spot. The colour of the naked parts
are adult-like as well.
The scapulars in 3cy are often completely adult-like, lacking internal patterns;
plain blackish grey with a mahogany hue on the older feathers. Most wing-coverts
and tertials are adult-like blackish grey as well, but often 3cy birds show some
very bleached pale brown wing-coverts, normally in the greater covert bar and in
the upper rows of the lesser coverts. These bleached wing-coverts accentuate the
jumpy sequence in the last wing-covert moult cycles, as there is often no clear
pattern in location of these bleached feathers. Head and body feathers normally
are snow-white by July.
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.
