Larus cachinnans 2CY-3CY PKBB October 2012 & February 2013, Germany & the Netherlands. Picture: Armin Deutsch & Maarten van Kleinwee.

Yellow PKBB and metal PLG DN-27656; 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).

PKBB is classic cachinnans.
