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.
C6H5 was ringed as pullus at Luopio, Finland on June 28 2001, now in 3cy. The inner primaries P1-P6 are glossy black with slightly paler inner webs and with well-defined neat white-grey tips. The outer primaries are paler bleached brown with only small white crescents on the very tip and are probably 2nd generation. Note the black markings on the tail-feathers, visible in the images. As can be seen in many 3cy fuscus, C6H5 has some retained bleached pale brown wing-coverts and one lower tertial. All secondaries and tail-feathers replaced as well.
