First autumn observation on harbour - Sep 28

Few gulls present. Next one, a YLG in primary moult and with a lot of streaks - both give more possibility to be of northern origin:

Two adults LBBGs present, both with no streaks on head. That and mantle colour indicate intermedius. This one in body moult:
And this one more advance - see head:

Four birds in 1st winter plumage gave close views, this one a northern YLG?:

A small birdf with sooty dark markings on mantle, probably Baltic?:

A quite pale bird, but still with dark mantle markings, heuglini?:

And a strange one with a "Caspian" type head:
