Juan Cabeza e-mailed yesterday with exciting news of a Guernsey-ringed Herring Gull at Boca do Rio, Porto do Sol, A Coruna, SPAIN on 9th February. White 5CK9 had been ringed at Chouet Landfill in May 2011, and had been seen at Sark Harbour in June 2012, indicating that this could be a breeding bird from that island. Although not unique it remains rare for Channel Islands nesting Herring Gulls to travel as far as North-west Spain each winter. The straight line distance of the movement is c 900 km!
