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). PHHV is classic cachinnans.
All scaps replaced and also coverts included in post-juvenile moult: inner GC, inner MC, inner and central LLC and random some LC. All flight feathers juvenile.
