LBBG 3cy NLA 5.366.284May 27 2003, Maasvlakte - Dintelhaven, the Netherlands. 

Ringed July 08 2001 as pullus at Missouriweg, Maasvlakte. This bird has moulted most of the upper-parts, prior to northbound migration. Almost all inner wing-coverts were included and still look relatively fresh, compared to the (10 months) older wing-coverts in the carpal edge. The central greater and outer lesser coverts are still much abraded (second generation) feathers. All scapulars have been replaced for grey adult-like feathers, but a few brown hued older feathers can be seen in the rear scapulars. The tertials are grey as well, the lower with a broad white tip. The fringes of the upper tertials are slightly worn. Soft parts acquired adult-like pigmentation with the bill showing a small black bill-band and bright red on the gonys. The legs are already yellow. The complete tail has been renewed to at least third generation as well, as all the rectrices are plain white. Primary moult has started in this individual: P1-P2 are missing. Note the head-moult, creating a 'moth-eaten' appearance.
