Larus cachinnans 2CY-4CY XNCD 2013-2015, France & the Netherlands. Picture: Pierre Tillier, Ran Schols & Willy Raitière.

Green XNCD and metal DEH (Hiddensee) EA..181624. Species: Herring Gull (Group) (Larus argent./cachin./michah.)
Ringed as pullus on May 30 2012 at REDDERN (2km NE), Oberspreewald-Lausitz, Brandenburg, Germany (51°42'00"N 014°06'00"E).

This colony is 100 km SE of Berlin and Lausitz holds a mixed colony in the lake. At this location ringing takes place in colonies of mixed species, with Herring, Caspian and Yellow-legged Gull, so identification is not always straight forward. The possibility that juveniles are not a pure bird is therefore not unlikely.
