Two visits to this site today thankfully yielded in the end a stonking first-winter Caspian Gull. It remained on site for over an hour as the tide slowly came in. Further scans produced a presumed second-winter, though a couple of features leave me in some doubt, though at the time this bird looked very promising.
Earlier in the week I managed to get over to the east of the county with the following highlights seen:
Red-necked Grebe - Camber
Hen Harrier - Scotney GP
Tree Sparrow - 20 at East Guildford
Taiga Been Geese - 5 at Pett
Pink-footed Geese - 4 at Pett + Barnacle Geese & Ruff
Cattle Egret - 2 at Tarring Neville
a huge first-winter Caspian Gull that showed well for over an hour
presumed second-winter Caspian Gull - the pale iris and shorter-legged appearance is slightly concerning but in the field the profile looked very promising. Yellow-legged Gull is the other option.
