Dear forum colleagues
Please can anyone advise about the attached photo.
They were seen by many including experienced birders in NW England and positively identified as a great scaup .
Of course it has to be a great scaup on that basis.
As an inexperienced birder I am enquiring - theoretically speaking, how can we positively eliminate lesser scaup. What can we see in this photo that eliminates lesser scaup please?
