P1-P10 new. Complete moult in coverts and tertials finished, gap in central GC closed. It is commonly seen that, while the outer primaries are replaced in the complete moult, a subsequent "partial autumn moult" will replace feathers in upper tertails and several inner wing-coverts in late summer and early autumn, which explains the fresher grey adult-like coverts seen in 2nd winter birds.

Active partial moult in this bird, note replaced MC, again much 2nd gen like in pattern.
