Yellow-legged Gull michahellis group, July 27 2001, Etaples, France (50.42N,1.34E).
Two 2CY's moult-stages clearly visible:
most of the inner secondaries have been shed (S1 already fully grown and
the inner half of the secondaries still juvenile) and only P9-P10 still
old (juvenile), while P8 is missing. The other 2CY has a similar moult-score.
In the foreground is a 3CY with P5
and P6 fully
grown. The inner greater coverts have been shed, exposing the second generation secondaries.
Again, this individual starts to show "winter-streaking" on the
head by late July. Note also the brown-based lesser coverts in the upper
row, the last obvious immature feathers in the wing-coverts panel.
