Hi Theo,
I'm not sure that I understand correct. From your point of view, which one is micha and which one is cachi?

Agree with Theo, this: http://www.birdforum.net/attachment.php ... 1290519370 - is a YLG on the features mentioned by Theo, and structure.
I don´t think the bill dimension is alarmingly altered in an angle like the one shown and with a shape like that it´s not a Caspian.
If the mirror is due to damage and renewed into a 3rd gen is a matter of opinion.

Still, I would like to see more shots of this bird, if possible. This kind of angle is one of the worst to judge bill shape correctly; the perspective may make the bill appear shorter and heavier than in reality.
The outermost primaries all look 2nd-generation to me; it would be very strange that damage would occur so symmetrically, in both wings.

Adriaens, Jan, Theo
Here are two more pics with the bird.

Well, can there be any doubt now?

i think no! but even with the first pic. show me a mich with such a big p10 mirror on 2nd gen primaries. bill was seen from a sharp angle so it was clear that it would 'stretchen' if seen from the side. very nice 2cy cachinnans indeed. told i them

Another shot by Christian taken on 32.Nov.

No doubt here either.

yepp, i agree but note stronger covert markings, no mirrors and shorter bill than in the previous.

Thank you for comments JanJ and Lou (happy birthday to you!).
On November 27th I visited again the gulls hot spot on Dambovita river . Soon, I will upload some new pics with (a lot of) Caspians Gulls and (some) Yellow-legged Gulls.
