Carlton walk but no photos

On Wednesday 7 May, late afternoon/ early evening, a 3 mile walk around Carlton Marshes failed to reveal any Grasshopper Warblers (But I did hear one reeling), never a showy species for me. 3 Swallows over the Whitecast track and a summer plumaged Great White Egret flew west over Share Marsh, a singing male Greenfinch in a bush by the path at the start of the Share Marsh track plus several Chiff- Chaffs, a Sedge Warbler actually showing quickly disappeared when a couple walked past me singing and a Roe Deer along the back track ended a somewhat disappointing visit with no photos taken.
