Caspian tern Hydroprogne caspia

A very average image of a Caspian tern in flight. Used to be called one name, now has this lot attached to it!

Hydroprogne caspia, formerly Sterna caspia; syn. Hydroprogne tschegrava, Helopus caspius

Wanted a better image, but the bright light exacerbated a migraine that wouldn't get better so this is it, then home!

I think it might be a juvenile as the marking and colours don't seem as intense as others I've photographed.
