...so I decided to try from a spot I'd noticed on the west bank and on arrival found another birder checking the water. Still no Smew but I lucked on to the Long-tailed Duck by the sailing club and we viewed that for a while before Carey, for that was the birder's name, pointed out a cracking male Goosander further up the lake. A consultation later and we were checking out another spot along the bank when fortunately he spotted the Smew with a few Tufted Ducks on the far side by the reeds, nice one Mr. Lodge! It stayed distant all the time I was there so this shot was the best I could do.
