(last update: May 17 2015)

Lesser Black-backed Gull graellsii S 13CY, July 08 2014, Maasvlakte, the Netherlands. Picture: Merijn Loeve.

Ringed as pullus in July 2002 at Maasvlakte, the Netherlands. Season 2002 several birds were ringed with single letter codes, the other leg should have another ring with letter E for Europoort; either white E (for Maasvlakte) or yellow E (for Dintelhaven). That E ring was lost over the years.

There are pictures of another (?) bird with only red S, observed in Katwijk for two years and believed to breed in that village: red S. It is probably another bird, as the shape of the mirror on P10 is slightly different.
