Re: GBBG or HG?

...or cachinnans. admittedly there's little in this bird (apart somewhat from bill shape) reminding of cachinnans but if we assume this bird is somewhere from western european russia, a combo of pale/contrasting herring gull plumage and some 'eastern genes' (whatever features they support or cosuppo...
