Abstract

The three widely recognized taxa of “white-winged” scoters Melanitta–fusca, deglandi, and stejnegeri are discussed variously in the literature as one, two, or three species. Adult males of the east Asian stejnegeri are distinguished from the American deglandi primarily by their black rather than brown flanks, yellow rather than black lamelle in the bill, and usually more hooked on the bill. Since 2002, there have been four well-supported records of stejnegeri in Alaska, two at St. Lawrence Island and two near Nome. Although we saw up to four adult males of stejnegeri at St. Lawrence Island in 2009, deglandi appears to predominate there. More study is needed for the status of stejnegeri as species or subspecies to be settled.
