One of the good things about ringed gulls: throughout the season you're pretty sure the same individual bird is involved all the time.
Therefore you can compare the plumage - like in Herring Gull Y[A||V], between early winter (1CY Oct) and late winter (2CY April), or if you like early and late 1st cycle plumage.
Yellow A||V nicely illustrates three issues:
- By October some 2nd gen scapulars are already slightly bleached to white; these are among the earliest replaced scaps right after the juvenile feathers are dropped.
- By April the feathers at this exact location is obvious greyish, and fresh. This is now 3rd generation.
- By late October the lower scaps are still juvenile, but not anymore in April. Therefore it illustrates that moult in the scaps continues throughout the winter months, albeit at low pace.
It supports also the assumption for 1st cycle Herring Gulls, that "if you find fresh scaps in the upper region or the upper row of the lower region, while the long rear scaps have been replaced, the aforementioned scaps are most probably 3rd gen".
