Hello,
Could you help me with these gulls?
I have a good feeling for the clean-head adult for Caspian and suspicion about the other adult for a Herring. The others (1st, 2nd and 3rd?) gull seems alright for YLGU to me.

Many thanks for your help in advance,

looks like you've got a recent influx from the north, rafnuss. most caspians still are north of frankfurt, most in the east (talking about germany). a few along the rhine now - and what really is interesting, you have a whole bunch of herrring gulls there (most birds in your pics) and 1 or 2 1st winter yellow-legged gulls. so, yes, adult cachinnans, at least one 1cy michahellis, an adult or subadult argentatus, many (3-4) 2cy HG and at least one 3cy or 4cy.

Thanks Lou,
As always very helpful.
Can you confirm that I found the correct ones on the picture?
I was unsure if there is not 2 3-4cy Herring?
Also, is the bird on the third picture a Caspian?

Many thanks

"?" looks like a michahellis but it's hard to be sure from this front view only; 2nd pic: correct apart from 1-2cy HG: it's at least 2cy; 3rd pic: left 4 birds correctly labelled, the "HG" is a 2cy and the rightmost bird a 2cy.
