Re: Pure cachinnans or hybrid?
plumage- and structurewise a good male 2nd cycle caspian. if there is argentatus in it, little shows up in this bird. hints of it could be (apart from the lacking p10 mirror, which a minority of caspians don't have): stronger than normal head striation and very short ventral p10 tongues for a 2nd cycle.

Re: Pure cachinnans or hybrid?
I would agree with Lou. However, that head shape with it´s pattern, fierce look and size of it could belong to a Herring.

Re: Pure cachinnans or hybrid?
Also, the rump is not pure white and the inner primaries are patterned more than I would like for a pure bird.
