观察细节
Pixelated photos. About the same size as adjacent Mallards. Also compared side to side with Gadwall, Hooded Mergansers, and scaup, Blackish brown plumage. Sloping head profile. Two large diffuse spots on head, one at the base of the bill the other behind the eye. White wing speculum visible about half the time. Long stiff tails. Unmistakable. Slept with heads tucked into back feather during most of the observation period. Raised heads a few times.
