This morning a Raven flew across the site, pausing on a pylon on its way. A Kingfisher was seen on the riverbank and there were two Grey Wagtails and four Little Egrets on the Ouse Dyke. Overhead there was a light passage of Swallows and House Martins, with some Meadow Pipits and Siskins. In the bushes there were still plenty of Chiffchaffs and a few Blackcaps, and a Jay was seen. PS.
