The common goldeneye or simply goldeneye (Bucephala clangula) is a medium-sized sea duck of the genus Bucephala, the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek boukephalos ("bullheaded", from bous, "bull" and kephale, "head"), a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin clangere ("to resound").
Common goldeneyes are aggressive and territorial ducks, and have elaborate courtship displays. The common goldeneye was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas clangula. Linnaeus specified the type location as Europe but in 1761 restricted this to Sweden. The common goldeneye is now one of three species placed in the genus Bucephala that was introduced in 1858 by the American naturalist Spencer Baird. The genus name is from Ancient Greek boukephalos meaning "bullheaded" or "large-headed". The specific epithet is from Latin clangere meaning "to resound".

Rare
Under 5% of wildlife watchers report a Common Goldeneye sighting in Gros Morne National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 130 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and December–January
In those months about 30% of wildlife watchers report a Common Goldeneye in Gros Morne National Park on a given day, against under 5% in March and June–September, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Goldeneye sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
26th of 41
Of the 41 parks where we can rate Common Goldeneye sightings, Gros Morne National Park ranks 26th at under 5%. The best odds are in Elk Island National Park (Canada, about 50%), Riding Mountain National Park (Canada, about 30%) and Isle Royale National Park (United States, about 30%). All parks ranked.
Same family: Anatidae
The closest relatives of the Common Goldeneye that you can see in Gros Morne National Park (family Anatidae, Ducks, Geese, and Swans) are American Black Duck (about 20%), Common Eider (about 20%) and Canada Goose (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Goldeneye is recorded against all the birds logged in Gros Morne National Park (80 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.
