The brant or brent goose (Branta bernicla) is a small goose in the genus Branta. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The Brent oilfield was named after the species.
The brant was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas bernicla. Linnaeus specified the type locality as Europe but in 1761 restricted it to Sweden. The brant is now one of six species placed in the genus Branta that was introduced in 1769 by the Austrian naturalist Giovanni Antonio Scopoli. The genus name Branta is a Latinised form of Old Norse brandgás, "burnt (black) goose". The specific epithet bernicla is Medieval Latin for barnacle.
The brant and the similar barnacle goose were previously considered to be the same species and believed to be the same creature as the barnacle. That myth can be dated back to at least the 12th century. Gerald of Wales claimed to have seen these birds hanging down from pieces of timber, William Turner accepted the theory, and John Gerard claimed to have seen the birds emerging from their shells...

Rare
Under 5% of wildlife watchers report a Brant sighting in Seattle on a given day, based on 2,220 verified sightings from GBIF citizen-science data. It is the 111th most-seen of the 271 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.
January to April
In those months about 10% of wildlife watchers report a Brant in Seattle on a given day, against under 5% in May to December, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Brant 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 16
Of the 16 cities where we can rate Brant sightings, Seattle ranks 4th at under 5%. The best odds are in Dublin (Ireland, about 20%), San Diego (United States, about 10%) and New York City (United States, about 10%).
Same genus: Branta
The closest relatives of the Brant that you can see in Seattle (genus Branta, Black Geese) are Canada Goose (about 40%) and Cackling Goose (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brant is recorded against all the birds logged in Seattle (2,220 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.
