what is it?

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.
