LBBG 3cy NLA 5.366.282May 07 2003, Maasvlakte - Dintelhaven, the Netherlands. 

Ringed July 08 2001 as pullus at Missouriweg, Maasvlakte. This bird has moulted all scapulars and several wing-coverts and tertials, prior to northbound migration. The central greater and outer lesser coverts are still much abraded (second generation-like) feathers. Soft parts acquired adult-like pigmentation but the bright yellow bill (red on the gonys) has a black bill-band. 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. Most rectrices replaced for third generation feathers which are almost completely white. The visible secondaries are old second generation. Odd primary moult with P4-P6 third generation and P1-P3 & P7-P10 old second generation.
