Guernsey Lesser Black-backed Gull seen at Portland Bill, England

LBBG Black 3.C5 at Portland Bill, England - Martin Cade

Martin Cade, the warden of the Portland Bill Bird Observatory, England sent me an interesting sighting today at the Bill of Lesser Black-backed Gull Black 3.C5, which was ringed at Chouet landfill, Guernsey on 28/05/10 (as part of the cannon netting operation run with Paul Roper and members of the North Thames Gull Group). It is believed that this is a Guernsey-nesting LBBG, and 120 km seems a bit far for a feeding trip for a bird which by now should be feeding chicks...so I'm not sure what the bird is doing at Portland. Perhaps it is a failed breeder this year? It will be interesting to see if it turns up back in Guernsey, before migrating for the autumn/winter.
