Hi JanJ,
I will check the pictures (it will take only a few minutes). I suppose that you want more pics with the 2cy bird, isn't it?

still a male adult cachinnans, jan. those amber coloured irides are very familiar for caspian and the ventral wingpattern in pic 4, post 2310 should leave no doubt. i think the dorsal tongues are there but not visible (hidden), mabye not as extended as in most cases. i often was surprized how micha like upperwing pattern can look in cachinnans when they just fly normally - inner webs being covered...

Yes, it is the same bird.

Yes Lou, maybe so. In spite of that we are not able to see p10 totaly free I think there´s a lot of blackish on the inner web and it would be nice to have a better view. I´m not especially in to suggesting a hybrid, just to be able to have a clear view regarding the variation. P9 pattern would provide no pronblem really.
Underwing pattern looks perfect.

I already uploaded a few pics taken in Herastrau on February 18th, as you can see in post #2289 (pag 92). I will try now to finish the job, uploading more pics from this series. The light was not so good as on February 17th, but I would say that the quality of the images is acceptable. So, the first 5 pics are here. The same bird in pics 2 and 3.

nice to see the difference between a 4th cycle (pics 1-2) and a 3rd cycle (pics 3-4). last one is a 1st cycle with some 3rd gen scaps.

"polish guy" among cristian's pics
starting to work on cristian's february pics i stumbled over this well documented probable hybrid cach x tatus.
not necessarily from poland (but cristian and james photogr. two 1st cycle cachs with polish rings at the same place as you know), since the intergradation zone is large (from poland in the west over lithuania, belorusia, ukraine to a large part of european russia). for argie-traits read the texts:

cristian - do you have more pics of this bird? maybe one showing its tail even better? (photo numbers: P2107357-83 on 10.02., P2117423-24, 31,35 and 683 on 11.02.)

February 27th - Some record shots of the Great Black-backed Gull from Herastrau. Sorry for the quality.
I suppose this could be the bird found there on March 1st 2011. See: http://www.talk.gull-research.org/viewtopic.php?f=24&t=520

yes, it looks like it could be the same (male) bird like last year when it stayed 20 days. gulls (especially vagrants) often are faithful to the same wintering/migration resting spots. nice to see the largest gull sp. in herastrau again. also, thanks for the additional pics of the presumed hybrid!

it's a cach anyway and one with this really cute simple scap pattern. was it really that dwarfy? i thought that dwarfy individuals occure in michahellis more or less regularly but hardly in cachinnans!
