Kittiwake
I found an adult Kittiwake today, on the water opposite the overflow. Initially I was viewing it from the far side, near the Beach Hotel, and it was super distant, but I went back at lunchtime and the bird was still present, so I managed to get some photos from the car, from Rakewood Road.
Quite a late one - we don't normally get Kittiwakes in June; it might even be the first June record.
