Amongst a small group of gulls that did pitch down at the lagoons was a third-winter Caspian Gull. Also a Norwegian colour-ringed Great Black-backed Gull put in an appearance and surrendered its code - JP600. In October and November 2012 it had been sighted on a couple of different oil rigs in the North Sea. Another colour-ringed GBBG was there but this one avoided having its colour-ring read. I did, however, manage to confirm the code of an adult Black-headed Gull that I first saw in December 2014. This one spends much of its time around the Ythan Estuary in Aberdeenshire.
