A bird was seen today on Astoria Sewage Ponds with clean,
white undertail coverts and a little poofy bit of feather
at the back of the crown. Unfortunately, it kept its bill
underwing the whole time that I watched it even when being
chased by other birds. This may well be the bird folks
have been reporting as a female TUFTED DUCK.

The male TUFTED DUCK was nearby, but I would not describe
them as being particularly interested in one another.
