Larus cachinnans 1CY PDEB November 20 2010, Deponie Pohlsche Heide - Minden, Germany (52°23'05N, 08°46'45E). Picture: Armin Deutsch.
Yellow PDEB and metal (PLG) DN18583, ringed as pullus on May 27 2010 at Kozielno, Paczkow, S-SW Poland, (50°29' N, 16°58' E).
In this area are mixed breeding colonies (near Katowice), with far most birds breeding here are cachinnans, but in this area also records of very few michahellis from the south (e.g. ringed female from Italy) and argentatus from eastern Germany are possible (see PDF). PDEB is classic cachinnans, although fresh 2nd gen coverts and scaps very boldly patterned.
