At the request of the Dutch rarity committee (CDNA), we have written a short paper about the identification of unringed Baltic Gull. The article, plus an accompanying web site, are found at:

Thanks a lot for this material, guys! I was puzzling with the small pictures in the magazine, but I love this new online section with pics wherein you can check the gen. of the primaries.

Hello,
My name is Slawek Karpicki. I am a new member of GRO forum. Most of my gull sightings are in the vicinity of Poznan (Western Poland). Also the birds in the attached photos are taken there.
According to the new article could some more experienced birder comment these two LBBG?
Dates of the sightings are in the photo titles.
Best regards
Slawek
