I randomly photographed two groups of scaup in flight to work on separating Lesser and Greater Scaup numbers here--both groups turned out to be Greater. That leads me to suspect that Rick Brigham's otherwise outlier count of 30 Greater Scaup yesterday is probably more in line with actual number of Greater Scaup here that most other estimates the past two days (including mine) which are generally 4 or less.
