As an extension to this topic, here are a few ringed Croatian birds I photographed in Łubna (central Poland, near Warsaw). In spring and summer, michahellis is (very) common here, about as common as cachinnans. Based on my personal ring readings I would say most birds originate from the Adriatic (rings from Croatia and Italy). In winter, YLG is surprisingly rare on the dump with just a few individuals among many wintering argentatus (most rings from Finland) and cachinnans (from Poland and further east). The sole ringed YLG I observed in winter was a Polish breeder.

These pictures are from May 2007.

Here are a few more, from August 2008.

While browsing for the ringed YLGs I found these two duos...

At Łubna today was about 2300 large gulls. Most was herring, about 90%.
I enclose a few photos from today.

Another trip, 30 january 2010, to Łubna brought some interesting obserwations.
Total about 2300 large gulls.

First picts of 2 hyperboreus. Adult bird its solid wintering resident at Łubna from few years. The 1winter bird was obserwed second time these season.



Few caspian gulls.





Herring gulls.


The same bird as above - open wings.


LBBG.


And some codes.

Nice series Michał! Looking at your pictures your hands must have been frozen Is the wing tagged Caspian from your previous series from Germany?

Hi Rudd!
All my pictures post at forum are digiscoped with hand held camera at scope - so the quality is not the best.
Additional there was hard strong wind at Łubna and two times my scope was fall down by wind...

The wing tagged A caspian is a bird signed by Grzegorz Neubauer.
Bird was cathed at rubbish dump at central Poland (Konin) at 1/12/2004 as 5cy female.
The bird was present at Łubna also at 2005 and 2007. Single record from each year.

Hi Michal,
seems to be really a paradise for gull watchers and ringreaders, that Lubna dump. Interestingly I have never read a ring of a bird that was at Lubna before, otherwise I had several gulls here, which had visited Konin dump earlier.

It would be fine if you could send me one of the hyperboreus - only for a few days , there is only one (proven?) record in Austria from the 1970ies.

Few photos from Łubna - YLG and fuscus.

Nice pics Michal! Could the birds named fuscus actually be smallish YLG´s? At least the second bird seems a bit too worn and advanced in scapular moult. And behind the first there´s a Caspian lurking.

Best regards
Hans
