The three Whooper Swans (plus four Mutes) were still present at the south end of the bog this morning, as were the two at Ystrad Caron.
Also three Little Grebes, two Snipe, a Little Egret, a scattering of Fieldfares and Redwings and a male Hen Harrier. I can't think of many finer sights than a hunting male Hen Harrier on a sunny winter's day.
