P1-P10. 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 missing MC, new inner GC and upper TT.

Scapulars replaced, limited moult in coverts (2x LLC). Tertials juvenile.
