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).

PNDT is cachinnans. Very irregular moult sequence, with jumpy pattern in GC, MC and upper LC. Scapulars too are a mix of (older) juvenile and recently replaced 2nd gen feathers. Already replacing upper tertials.
