Leucistic Great Black-backed Gull

A leucistic Great Black-backed Gull was present at Chouet on Friday morning. Although I've seen a handful of Lesser Black-backed Gulls with varying degrees of leucism, this is the first GBBG I've seen with this condition.
Leucistic GBBG Chouet Landfill Beach - 18 March 2011 - PKV
Amongst the 400+ Lesser Black-backed Gulls on the beach were 54 of my colour ringed birds, including several more back from winterng in Iberia and France.
There was also evidence of further movement of Great Black-backed Gulls with two more of Gilles Le Guillou's colour ringed birds from Seine-Maritime, France - 57H Black (new) and 28E Black (seen previously in Guernsey).
