Caspian Complex and more :)

This subadult Caspian was also in "Armenian post":

In the next a Caspian resting with a darker individual to the left, what?:

Is the same individual as in a previous post:

Here alone, very dark Caspian, Steppe or heuglini? or even taymyrensis? :

At least adult Caspian looks easy!:

A bird that I think is a Steppe one:

But I cannot say what is that... another Steppe or a very dark Caspian ?


Finally a bird that looks really huge beside the Baltic one:

I suppose is an hybrid YLGxCG (mirror/primaries, body colour and eye like Caspian, legs and bill like YLG).
