3rd. 2 Greenshank HT+ at merse head. Tens of Pied Wagtail all over the flats. Maybe 300 Wigeon or more, 4 Little Egret, c40 Lapwing. Probable Grey Plover juv but its behaviour didn't recall GP for me. Nor Golden P. Noticeable dark cap/crown, dark primary tips, whitish forehead & supercilium behind the eye.
