Summary ²

The long-tailed duck (Clangula hyemalis), once known as oldsquaw, is a medium-sized sea duck. It is the only living member of its genus, Clangula. This was formerly used for the goldeneyes, with the long-tailed duck being placed in Harelda, but the latter is the type species of the genus. An undescribed congener is known from the Middle Miocene Sajóvölgyi Formation (Late Badenian, 13–12 Mya) of Mátraszőlős, Hungary.
