Hello Margaret, as far as I know there have been no Scaup sighted at Abberton in the last week, plenty of other interesting ducks, Red Crested Pochard, Ruddy Shellduck, Garganey, Goldeneye and lots of diff waders from both causeways. When was your photo taken? I usually see Scaup there around end of & beginning of the year.
