5.293.8?? adult LBBG, July 14 2002, Dintelhaven, Maasvlakte, the Netherlands.

Ringed with a Dutch ring: Arnhem 5.293.8?? P1 and P2 have been shed. The tips of the outer primaries are relatively fresh.

Unfortunately, it wasn't possible to completely read the ring code, but this is a Dutch Lesser Black-backed Gull, probably ringed as pullus in the colony of Maasvlakte or IJmuiden.
At same spot, another Arnhem ringed bird (partly read) was present on this day, missing primaries p1-p3.
