Barrow's goldeneye (Bucephala islandica) is a medium-sized sea duck of the genus Bucephala, the goldeneyes. This bird was named after Sir John Barrow. The genus name is derived from Ancient Greek boukephalos, "bullheaded", from bous, "bull" and kephale, "head", a reference to the bulbous head shape of the bufflehead. The species name islandica means Iceland.
Barrow's goldeneye was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the ducks, geese and swans in the genus Anas and coined the binomial name Anas islandica. Gmelin based his description on the "Hravn Oend" that had been briefly described in 1776 by Danish naturalist Otto Friedrich Müller. Barrow's goldeneye is now placed with the common goldeneye and the bufflehead in the genus Bucephala that was introduced in 1858 by American naturalist Spencer Baird. The genus name is derived from Ancient Greek boukephalos, meaning "bullheaded", from bous "bull", and kephale, "head". The specific epithet islandica is for Iceland. The species is monotypic: no subspecies are recognised.

Possible
About 20% of wildlife watchers report a Barrow's Goldeneye sighting in Jasper National Park on a given day, based on 357 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 156 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and May
In those months about 50% of wildlife watchers report a Barrow's Goldeneye in Jasper National Park on a given day, against under 5% in December, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Barrow's 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.
3rd of 19
Of the 19 parks where we can rate Barrow's Goldeneye sightings, Jasper National Park ranks 3rd at about 20%. The best odds are in Yellowstone National Park (United States, about 30%) and Wrangell-St. Elias National Park (United States, about 30%).
Same genus: Bucephala
The closest relatives of the Barrow's Goldeneye that you can see in Jasper National Park (genus Bucephala, Goldeneyes and Bufflehead) are Bufflehead (about 10%) and Common Goldeneye (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Barrow's Goldeneye is recorded against all the birds logged in Jasper National Park (357 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.
