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).

PKSB is classic cachinnans. Bird in complete moult: P1-P4 fully grown, P5 growing, P6-P7 missing, P8-P10 old juvenile. Moult gap in central GC, exposing old juvenile secondaries underneath.
