Possible hybrid LBBxHerring? Cheshire.
Thoughts on potential hybrid. Obvious male displaying and seemingly paired with a Herring Gull. Pictures here.

no replies so far, so i'm gonna answer here too: have a look at many pics of this combination here: http://waarneming.nl/soort/photos/20507#
adult looking LBBGs (or darker mantled large gulls with structural resemblence to LBBG) with pinkish legs usually are considered to be of this hybrid type. at least in holland. but we had a discussion about adult or nearly adult (3rd/4rth cycle) graellsii types with pinkish legs in britain. some people consider this within variation of LBBG.
