Larus cachinnans P342 2CY-3CY, July 2014 & February 2015, Rotterdam, the Netherlands. Picture: Cornelis Fokker & Merijn Loeve.

No data yet, but probably Green P342 and metal (PLG) DN22406, ringed as pullus on May 24 2013 at Kozielno Paczkow Opolskie Poland (50°28'35" N,  16°58'54" E). This is a mixed breeding colony in Poland, with most birds breeding here cachinnans, but in this area also records of very few michahellis are possible (see PDF). P342 obviously classic cachinnans.
