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). PETC is classic cachinnans.

Dark bold pattern on grey new scaps. Post-juvenile moult included inner coverts: GC1-2, MC1-8 (except MC3), LLC1-2 and single LC's. In left wing also TT1-2 replaced.
