Probably this hybrid. Obviously darker grey than local Herring Gull argenteus and with obvious yellow tone in legs. Full broad band on P5, limited white in wingtip.
But also some Herring traits: orbital ring not coral red, rather orangey. Red gonys spot limited to lower mandible.

Upperpart grey tone is too dark for argenteus. Combination of yellow(ish) legs and deep red orbital ring (is orange-yellow in argenteus), broad medial band on P8, and broad band on P5.
