An individual which clearly replaced upper tertials and wing-coverts 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, with new third generation feathers still showing a second generation-like pattern, but with broad neat fringes.

The partial autumn moult included the upper tertials, the innermost greater coverts, most of the visible inner median coverts and lower lesser coverts and a couple of inner lesser coverts. The feathers in the carpal edge and most of the outer wing-coverts are still juvenile.

The bill is still most dark, but the base already turns paler. Compare with the (typical average) 2cy michahellis in the background.
