Yellow-legged Gull michahellis 1CY 025K November 27 2003, Port la Nouvelle, S France.

025K has only replaced a few wing-coverts and tertials in the post-juvenile moult. Almost all the scapulars have been replaced for second generation feathers, except the rear lower scapulars, the ones covering the scapular coverts. In the upper scapulars, a subsequent moult to third generation feathers has started, with third generation grey-based feathers, with broad neat fringes.

The partial autumn moult excluded the tertials and greater coverts; but included two median coverts, three lower lesser coverts and a couple of inner lesser coverts. All remiges and rectrices are still juvenile.

The bill is still completely dark.
