What I believe is the same bird as the one in this video, as been accepted as a Glaucous-winged Gull, the fourth British record.
The bird has been 'accepted' only from Beddington Farmlands on 21st-22nd April 2009. However, what is believed to be the same bird was also seen at Queen Mother Res, Calvert, Willen, Rainham, and Ware between 3rd February 2009 and its last date at Beddington. A remarkable looking gull seen at a remarkable set of sites.
More info can be found on Peter Alfrey's blog with plenty more chat from Peter here and here and here and here. Some more photos of this bird can be found on Birdforum too. Lee Evans also has a little to say here.
If you want to see all of my photos and video of this bird when it was at Stewartby Lake between 9th-11th March 2009, click here.
