There’s usually no problem finding the American Wigeon in the Lower Mainland during the winter. The males are identifiable, by the white patch on their forehead and green face patch. I do get the females and the juveniles mixed up though as they look identical, although I believe on the females the black tip on the beak is more developed.
Fact: “The American Wigeon was formerly known as “Baldpate” because the white stripe resembled a bald man’s head.” [allaboutbirds.org]
