Lesser Scaup x Pochard at Lough Murree

I headed out to Newquay and the Flaggy shore to see if any wildfowl was in the area. On Lough Murree
were a pair of Greater Scaup, a handful of Pochard, Tuftys and plenty of Wigeon  and a Hybrid duck  which had me confused, luckily  here I met Dermot Breen, who has a good knowledge of ducks and we observed the bird showing signs of  Lesser Scaup x Pochard.
