The long-tailed duck (Clangula hyemalis) is a medium-sized sea duck that breeds in the tundra and taiga regions of the arctic and winters along the northern coastlines of the Atlantic and Pacific Oceans. It is the only member of the genus Clangula.
The long-tailed duck was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with all the other ducks in the genus Anas and coined the binomial name Anas hyemalis. Linnaeus cited the English naturalist George Edwards's description and illustration of the "Long-tailed duck from Hudson's-Bay" that had been published in 1750 in the third volume of his A Natural History of Uncommon Birds.
This duck is now the only species placed in the genus Clangula; the genus was introduced in 1819 by the English zoologist William Leach to accommodate the long-tailed duck, in an appendix on species to John Ross's account of his voyage to look for the Northwest Passage. The genus name Clangula is a diminutive of the Latin clangere, meaning "to resound". The specific epithet hyemalis, also Latin, means "of winter". The species is considered to be monotypic – no subspecies... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Long-tailed Duck is recorded against all the birds logged in Saint Petersburg (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
