As I arrived yesterday morning, 30+ snipe rising from the marsh announced the presence of a young Hen Harrier. This bird continued to harass snipe and ducks while I was there, at one point landing on the reeds immediately in front of the Britton hide. No swans on this visit but plenty of Mallard, Wigeon, Shoveler, 4 Tufted Duck a Gadwall and loads of gulls (mainly Herring).
