Afterwards I decided to check if there were any Gulls in the Cuckmere. Approaching from Chyngton Farm I was pleased to see a large gathering in front of me, and was even more pleased when I found a juvenile Glaucous Gull mixed in. Setting up the scope a further scan produced 2 Caspian Gulls (1w & 2w), but then all the Gulls got flushed and most headed inland, some out to sea with only a couple of hundred remaining, that included the second-winter Caspo. I didn't see the Glauc again, but thankfully ADW found presumably the same bird at Arlington roughly half-hour later.
On the 11th I was on standby and decided to wait up at LGW right on the Sussex border. I found a pair of Ring-necked Parakeets straight away but they were in a tree bang on the border and the branch they were on seemed to be overhanging into Surrey. My best attempts couldn't get them to fly south, so I had to keep on walking around. Fortunately it didn't take too long before another pair done the decent thing and flew into Sussex.
