112X has obviously replaced wing-coverts and tertials in the post-juvenile moult. All scapulars have been replaced for second generation feathers, including the rear lower scapulars, the ones covering the scapular coverts. In the upper scapulars, a subsequent moult to third generation feathers has started (1-25% replaced), with third generation grey-based feathers, with broad neat fringes.

The partial autumn moult included the four upper tertials and four inner greater coverts. Almost all inner visible median covert have been replaced, nine lower lesser coverts and about 60% of the lesser coverts have been replaced as well.

The bill is still completely dark.
