Yellow PKLP and metal PLG DN-28654; 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).
PKLP is classic cachinnans.
Last moulted scapulars are greyish without much pattern. Only single feathers in covert panel replaced.
