No, Ive shoot a fair amount of widgeons and can easily identify them. The bill is shaped like a mallards, but completely black. Widgeons have a shorter, more pointed bill. The rump on this one was real short and stubby. The only duck it somewhat resembles is a lesser scaup hen, but Ive never shoot nor seen them on the pond before. Heres a picture of the scuap for reference. The speculum are very similar.

The only thing is that it was darker than this. If anyone shoots scaup, tell me if you think thats what it is.
