I saw two Scaup (male and female) at Colchester Pond this afternoon.  This
is my first time seeing Scaup and am not sure if they were Lesser or
Greater.   I took a few pictures, but they were too far away to get a good
clear shot.  Based on Ian's post describing 3500 Lessers and 4 Greaters a
few days ago, I am inclined to think that the odds are in favor of the two
I saw being Lesser?
