A very quiet day on the land but the sea came to the rescue with a juvenile Long-tailed Skua quickly passing through off the fishing boats and in the evening with a very large feeding gathering of Sandwich Terns and Gannets and a few associated Mediterranean Gulls and Arctic Skuas. A juvenile Caspian Gull was also on the beach. Of interest on the land were a juvenile Cuckoo and a Whinchat and 31 Yellow Wagtails and four Grey Wagtails passing overhead.

Ten Porpoises and two Grey Seals were feeding offshore.
The moth traps provided plenty of excitement with the rare pyralids Hellula undalis (second Observatory record) and Loxostege sticticalis (eighth Observatory record), nine Box-tree Moths, a Convolvulus Hawk-moth, three Cypress Pugs and a Delicate.
