The upper tertials, three inner median coverts, few lesser coverts have been moulted to third generation grey-brown feathers. Note again the coloration of the bill; a very faint red tinge is visible at the gonys. Second generation primaries have delicate white tips, while P10 shows a very small mirror (more of a tiny spot). A mirror on a second generation P10 is at least not usual, since we have seen only a few individuals (including one colour ringed individual from the Maasvlakte, the Netherlands).
