The bot-belly, short legs and 'facial expression' remind me of Glaucous. Also the primaries were paler brown. Or is it just the bill? Amsterdam, 25-10-09.

One more Herring from the paler end, Heemskerk 31-10-09. Don't see any Glaucous influence here.

Nelson B1 and B2 may very well have a GBBG as a parent.

Thanks Theo for answer. This bird indeed doesn't looks like other "typical" hyperargentatus, but I have seen only few pictures of hybrid with GBBG.
Can you explain your presumption, is there any diagnostic details (bil, plumage pattern)?
Do you know any sites with pictures of hybrids?
One more pictures of this ineresting gull.
