Larus cachinnans 2CY PKSE March 21 2013, Deponie Pohlsche Heide - Minden, Germany (52°23'05N, 08°46'45E). Picture: Armin Deutsch.
Yellow PKSE and metal PLG DN-28698; ringed as pullus on May 25 2012 at Kozielno, Paczkow, S-SW Poland, (50°28' 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).
PKSE is classic cachinnans. All scapulars and several inner and central wing-coverts replaced in post-juvenile moult.
