Amongst only 24 Black-headed Gulls at the Richmond end of Vazon today were a British colour ringed juvenile (White 21J0) and the same Polish metal-ringed adult (Gdansk FN75.807) that I saw on both the east and west coasts of Guernsey last August/September. The bird was ringed as a chick at Januszkowice,Zdzieszowice, Opolskie, POLAND on 17 May 2008 (J. Siekiera). Few other cr gulls were recorded on another wet and blustery morning in Guernsey - whatever happened to summer?!
