Larus cachinnans 2CY PHZL November 28 2012, Deponie Pohlsche Heide - Minden, Germany (52°23'05N, 08°46'45E). Picture: Armin Deutsch.
Yellow PHZL and metal PLG DN-27630; ringed as pullus on May 26 2011 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).
PHZL is classic cachinnans.
Very dark brown on primaries and secondaries. Only faint mirror on P10.
