3cy graellsii, ringed at Europoort, Rotterdam (51.57N 04.06E) in 2004. There should be another ring with a unique code, but that one was apparently lost. However, in all respects typical local 3cy LBBG, probably with the inner two or three primaries missing and all secondaries worn second generation. At least several tail-feathers are still old second generation, which is not surprising considering the largely old, immature patterned wing-coverts.
