Great Black-backed Gull siblings go in opposite directions

Recently on this blog I reported that Great Black-backed Gull Yellow 0T1 had been seen at Le Portel Beach, Pas-de-Calais, France. Today on Chouet Beach, Guernsey I saw this bird’s sibling (Yellow 0T3). These gull chicks were ringed in the same nest on Little Burhou, Alderney on 10 July 2009. However, while 0T1 has gone some 300 km east up the English Channel, its brother or sister went at least 225 km in the opposite direction to be seen firstly at Dawlish Warren, Devon, England on 22nd August 2009 (Lee Collins) and then at Porthleven, Cornwall, England on 08 November 2009 (Ray Poulding).

GBBG Yellow 0T3 Little Burhou - July 2009 - C Mourant
GBBG Yellow 0T3 Chouet, Guernsey - July 10 - PKV
In recent weeks I have been visiting various seabird colonies around the Bailiwick of Guernsey, so my visits to Chouet landfill and its adjacent beaches have been curtailed. What was very noticeable this morning, on my first visit in several weeks, was the increase again in Great Black-backed Gulls (50+ birds) - including many immature birds.
