I managed to find time to visit the evening gull roost once again and today, in the wake of the Caspian Gull find yesterday I had company with up to four other birders around including Ewan Urquhart, Peter Law and Jarrod Hadfield. Together we enjoyed good views of the adult CASPIAN GULL again which was in the roost from reasonably early on. There were also at least four YELLOW-LEGGED GULLS (2 adult, 1 1w & 1 2w) in amongst the usual suspects. Other birds included 5 DUNLIN, 2 REDSHANK and 1 PINTAIL (per Ewan). Peter Law also reported 3 GOOSANDER on the Thames up at King's Lock.
The Caspian Gull - it's certainly got the "phwoar factor" in my book!
