photo 1334: Yellow-legged Gull michahellis 2CY, June 14 2002, Etaples, NW France. The
individual below is very reminiscent of the two bird depicted left and
right, although moult in the wing-coverts is much more ahead. Primary moult stage:
P7 has been shed and P8-P10 are still juvenile. P5 is at the final length
(visible beneath the lower tertials) and P6 is growing. Most of
the wing-coverts have been renewed. The gaps at the
central median and the central greater coverts will be closed soon at
about covert #7 or #8, which are currently still not fully grown. The upper tertials are replaced as well. This individual is illustrative for 2CY michahellis
moulting to 'barred' birds by the end of June, early July. See e.g. this
2CY from the end of June. All upper
scapulars and most of the lower scapulars have been moulted to new barred scapulars and the
scapulars in the lowest row are still growing. Last old wing-coverts can
be found in the upper rows of the lesser coverts, but considering the
pretty neat and jet-back centres, these lesser coverts may have been
moulted once before, and are currently second generation feathers. |
