In January, the astonishing news broke that a Glaucous-winged Gull Larus glaucescens had been seen, trapped and ringed at a landfill site in Gloucester. Unfortunately, it was not seen again. This was a species which had been predicted to occur in Britain, following previous records from the Canary Islands and Morocco.

BUBO Listing is adding Glaucous-winged Gull as a provisional species to lists of all four authorities, in advance of official acceptance. Should the record be rejected then the species will be removed, along with any records of it.
