I just wanted to add that not all female Tufted Ducks have white undertail
coverts. According to "Waterfowl" by Madge and Burn, only female variants
have them. Males are neither mentioned as having them in the very detailed
text, nor are males depicted in the illustrations as having them. I don't
know how common those female variants are, but the bird seen today
definitely showed white undertail coverts.
