I noticed a colour-ringed Herring Gull at New Quay yesterday, Blue JBY. The Severn Estuary Gull Group have just sent me its details:
It was ringed as a first winter bird in January 2010 at Stoke Orchard landfill site in Gloucestershire and seen subsequently in February, March and December 2010 at Gloucester L.S. Yesterday's sighting was the first since then.
In recent years we have had a few Herring Gulls on the Ceredigion coast which have been ringed in Gloucestershire.
