4 images: LBBG 3cy C00June 18 2005, Amsterdam, the Netherlands. Pictures Ruud Altenburg. 

3cy graellsii, ringed at Europoort, Rotterdam (51.57N 04.06E) on June 26, 2003. This bird has a complete third generation tail and has replaced many wing coverts and all tertials. Age of secondaries and inner primaries is best judged in stretching and preening birds. C00 shows 25-50% third generation secondaries. In these pictures, some are visible protruding beyond the greater coverts. P1 is new (not visible in this picture), P2-3 are missing and P4-10 are of second generation.
