Two another gulls (Podhale, Poland, yesterday). One - very dark (6973) and second (6974) (both on the same picture 6972) with "dark eye" - yellow - legged?

hi Michal, the one with the dark smudge around eye looks like the only michahellis among these, the rest being cachinnans including the dark 1cy.
michahellis by tail pattern and eye smudge, also belly line. cachinnans (the dark one) by pronounced collar/boa, almost concave belly (between two bumps), pale axilliaries and large pale greater covert tips.

Finally, there's michahellis, and of course, thanks for the explanation too
