The bufflehead (Bucephala albeola) is a small sea duck of the genus Bucephala, the goldeneyes. It breeds in Alaska and Canada and migrates in winter to southern North America. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Anas albeola.
The bufflehead was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas albeola. Linnaeus based his account on the "little black and white duck" that had been described in 1747 by the English naturalist George Edwards in the second volume of his A Natural History of Uncommon Birds. Edwards examined a specimen from Newfoundland provided by the archivist George Holmes (archivist), the deputy Keeper of Records in the Tower of London. Linnaeus specified the type locality as America, but this has been restricted to Newfoundland following Edwards. The bufflehead is now placed with two goldeneye species in the genus Bucephala that was introduced in 1858 by the American naturalist Spencer Baird. The genus name is derived from Ancient Greek βουκέφαλος bouképhalos, 'bullheaded', from boûs 'bull', and kephalḗ... Wikipedia →

Possible
About 20% of wildlife watchers report a Bufflehead sighting in Yellowstone National Park on a given day, based on 1,357 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 197 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.
January and May
In those months about 40% of wildlife watchers report a Bufflehead in Yellowstone National Park on a given day, against under 5% in November, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Bufflehead sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 37
Of the 37 parks where we can rate Bufflehead sightings, Yellowstone National Park ranks 4th at about 20%. The best odds are in Elk Island National Park (Canada, about 50%), Channel Islands National Park (United States, about 30%) and Riding Mountain National Park (Canada, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Bufflehead is recorded against all the birds logged in Yellowstone National Park (1,357 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.
