I finally caught up with this GREAT WHITE EGRET this afternoon, thanks to Jim Gurney and Roy Dunham. Despite dipping twice on the bird at Roxton River Pit, I eventually saw (and photographed) it when Roy relocated it on the main pit; it's stay was very short-lived though - the bird flying west to roost on the islands of the River Pit at 3.45pm.
These two drake GOOSANDERS were present on the River Pit...
At Blunham Lake, a single Little Egret was roosting on the island, with 6 Grey Heron present, 106 Greylag Geese, 70 Mallard, 8 Gadwall, 34 Wigeon, a drake Shoveler, 84 Tufted Duck and 62 Pochard
Roy had also located the Pink-footed Goose with Greylag just west of Peacock's Lake, Broom, but there was no sign of it when Jim Gurney and I looked shortly later (nor of the wintering male Merlin)
