Tufted Ducks, but no Lesser Scaup :(

On our way to Cardiff we stopped of at Cosmeston Lakes for an hour. Unfortunately I couldn't find the  drake Lesser Scaup during the visit. On the lake there were 4 Great Crested Grebes, 6 Pochards and 2 Gadwall. Also, there were 3 groups of Tufted Duck on the lake in all about 30, (15 drakes, 10 females, 5 first winter females) the drakes got very close at times
