I only gave it half-an-hour or so at Goring Gap first thing, and indeed it felt quiet but I did record the first Grey Wagtail, Redshank and two Swallows of the autumn, along with 78 Gannets, two Sandwich Terns, three Swifts and two Mediterranean Gulls (one juvenile).
A very quick stop at the toll bridge overlooking the Adur Estuary produced little other than two Little Egrets, nine Mute Swans, two Oystercatchers, a Sparrowhawk, a Skylark, a Linnet and two Pied Wagtails.
While sitting in the garden having dinner early evening, at least two Mediterranean Gulls hawked overhead with Black-headed Gulls.
