Notes on distinguishing males of White-winged Scoter, Velvet Scoter, and Stejneger's Scoter

  • Velvet Scoter (M. fusca): the least knob on the bill, and the least white around and behind the eye; almost no white above the eye. The coloured section of the bill is yellow and relatively long, and the distance from the base of that to the eye is short, producing the impression that the eye is positioned relatively far forward on the head. The crown looks highest above the eye.
  • White-winged Scoter (M. deglandi): clear knob at the base of the bill, with the yellow-orange part relatively short, so that the eye looks set further back on head than Velvet Scoter. The white around the eye is shaped as a checkmark, pointed up at the rear end. The coloured part of the bill is orange with the top parts looking yellow. The crown is highest in front of the eye. When seen well, flanks will be brown in contrast to black back and breast.
  • Stejneger's Scoter (M. stejnegeri): Head shape closer to Common Eider in shape, with a long, sloping forehead. White around eye similar to or longer than White-winged Scoter. It has a clear knob - almost like a small Rhinoceros horn - on the bill, further forward than M. deglandi, and the coloured parts are mostly red with yellow "lipstick" below. Flanks are black

Females are much harder to distinguish, only determinable at the closest range; Velvet Scoter has a slightly concave forehead with no basal swelling on the bill, Stejneger's Scoter has a slightly swollen bill base, and White-winged Scoter a marginally more swollen bill base.


In flight, it shows a white patch on the rear of the wing.


Northern North America; winters to coastal southern USA


This is a monotypic species[1]. Formerly considered conspecific with Velvet Scoter from Northern Eurasia and Stejneger's Scoter from East Asia.


Breeds around fresh water bodies near boreal forests and arctic tundra; sometimes far from the coast. Outside of the breeding season, they are to be found in coastal waters, often near shellfish beds



Slower and more powerful than Common Scoter.


Their diet includes shellfish, crabs, sea urchins, fish, insect larvae and plants.


They build a lined nest on the ground near lakes or rivers, in woodland or tundra. The clutch consists of 7-9 eggs.


Usually silent
