617V shows an average amount of 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 both the upper and lower scapulars, a subsequent moult to third generation feathers has started (1-25% replaced), with the third generation feathers still very second generation-like in their pattern, but again with broad neat fringes indicating freshness.

The partial autumn moult in tertials and wing-coverts in the left wing: tertials #1-4; greater coverts #1-5,7; median coverts #1-13,19; lower lesser covert #1-5 and most of the visible lesser coverts (60%; 70% of the lessers visible). Outer lesser coverts and the upper row may still be juvenile.

The bill is most dark, with a paler tip.
