Hi
This juv gull puzzles me for two reasons - a complete white bottom and an almost uniform black collar - again some kind of Caspian hybrid (as always - Poland, Podhale, today).
So please help !

Hello Michal,

yes, I agree with you, how pure=ID book like must a Gull looking to name it a Caspian Gull in Poland.

It looks ok for a 1cy=1st cycle Caspian Gull for me, but experts might well find some Herring Gull influence? Thanks from me too!
