I think it is a "Larus polonicus", because the tertials are typical cach-like. Unfortunally there is no colour-ring.

Re: micha or cach x tatus?
ok, anybody thinking it could also be a michahellis (like me?). i don't see anything that separates it from YLG. head would be allright after postjuvenile moult and bold double anchors are there on scaps. some michas can show such tertial crecents also....
