Fine, thanks for that link ;) !

Just yesterday I tried to open other websites of Grzegorz, but it seems they don´t work now.

Btw: One of these crossed my ways - 896P, 6.1.2006, Wörth/Austria. It has got it´s cr in 2004.

Note the differences in p5 and p10.
Where there is a large variation on p5 (with many not showing the bar) there is much more consistency on p10.
50P3 would not make it when I would see it in Holland.
The combination of p10, p9 and p5 are indeed a rare type.

This one was present on December the 24th on the rubbish dump of Barneveld. With only a faint black spot on p5 and a light iris.

Yesterday this one at Lake Traunsee (northern Alps), Austria.
Much white on P9, "broken" black band on P5, but also black on P4 (only left wing).

very nice pic of a beautiful and odd caspian, wolfgang. i suppose you have quite a good collection of own pics to compare the frequency of such birds , e.g. with incomplete p5 marks? hard to interprete anything "in it", it may just be one of the phenotypic varieties, but why this is and since when and if by influences of other taxons? we don't know. :cry:
