P10 fully grown. All tail-feathers fully grown. Greater covert #3, median covert #4 and most central coverts, lower lesser covert #2 and just one lesser covert included in the partial autumn moult. The feathers are obvious more grey, although the anchor pattern is also visible in most of these fresh feathers.
