Lesser Black-backed Gull graellsii EN24 7cy, April 22 2002, Missouriweg - ECT, Maasvlakte, the Netherlands (51.59N,04.02E). 

An adult ringed, left orange EN24. This bird was ringed as a pullus July 1996, near the current breeding spot. Probably a male as the strong, powerful impression suggests. Note the small white tips and the hint of a black bill-band near the gonys. This bird is probably paired with a white ringed LBBG SP3.
