CR-ringed large gulls [Belorussian & Finnish]

Just have recived an email from Piotr Zientek, who's at Ujście Wisły up to now. On the 2nd of November 2010 he saw two interesting cr-ringed gulls in Jantar. First Belorussian Herring gull (Larus argentatus) was carrying a ring - KA53 and Great Black-backed gull (Larus marinus) from Finland (CC111).We are waiting for ringing data.
