Behavior of bird: 

Mixed in with a small flock of scaup and 1 Surf Scoter as part of longer broken string of scaup flocks spread along Holly Beach.Flocks were just beyond rock breakwaters parallel to beach in this area.Bird was initially seen sleeping, and white eyespot seemed to indicate this species.After a few minutes of observation it lifted its head, preened and flapped, and then drifted along with the flock.Mac noted that the scoters drifted to the W more quickly than the other ducks in the flockónoticeably so.They must have been swimming instead of drifting, even when their heads were down.

Description:

Blackish duck with orange tip to bill and large white wing patches.Bird was much larger than scaup in flock, and larger than Surf Scoter it was often next to.

 

Neck and head dark blackish, with white eyespot; I donít know if this was the eye color or feathering.Black feathering of nostrils extending about 1/3 of the way onto bill; bill otherwise orange.I couldnít detect other colors in the bill as the bird was active and the seas had a bit of wave.I was also concerned with getting pictures when the birdís head was raised.

 

Body color a worn dark brown or brownish-black.Initially, the white of the wings was hidden on the sleeping bird, but apparently the bird shifted its body and the wing patch was revealed.When the bird flapped, it revealed white secondaries forming a large rectangular white patch there.The tail seemed worn, and appeared to be very pale as well.

 

In one photo, the bird is seen rising up, opening its bill to reveal a pale mouth lining, and flapping.The white wing patches are also visible in this shot.
