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 →

Rare
Under 5% of wildlife watchers report a Long-tailed Duck sighting in Wrangell-St. Elias National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 81st most-seen of the 93 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Long-tailed Duck in Wrangell-St. Elias National Park on a given day, against under 5% in February–April and July–September, the lowest months. October to January have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Long-tailed Duck sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 16
Of the 16 parks where we can rate Long-tailed Duck sightings, Wrangell-St. Elias National Park ranks 6th at under 5%. The best odds are in Svalbard (Norway, about 30%), Acadia National Park (United States, about 10%) and Cape Breton Highlands National Park (Canada, about 10%).
Same family: Anatidae
The closest relatives of the Long-tailed Duck that you can see in Wrangell-St. Elias National Park (family Anatidae, Ducks, Geese, and Swans) are Green-winged Teal (about 30%), Trumpeter Swan (about 30%) and Mallard (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-tailed Duck is recorded against all the birds logged in Wrangell-St. Elias National Park (9 verified sightings from 2019 to 2026), 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.
