The majority (~70%) of the global population breeds in Wisconsin, Minnesota, and Manitoba. Golden-winged warbler populations are slowly expanding northwards but are generally declining across its range. This is most likely as a result of habitat loss and competition/interbreeding with the very closely related blue-winged warbler, Vermivora cyanoptera, albeit the latter point has been debated. Populations are now restricted to two regions: the Great Lakes and the Appalachian Mountains.
The golden-winged warbler was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Motacilla chrysoptera. The specific epithet is from Ancient Greek χρυσοπτερος/khrusopteros meaning "golden-winged", from χρυσος/khrusos meaning "gold" and -πτερος/-pteros meaning "-winged". Linnaeus based his entry on "The golden-winged fly-catcher" that had... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden-winged Warbler sighting in Minneapolis [Saint Paul] on a given day, based on 473 verified sightings from GBIF citizen-science data. It is the 116th most-seen of the 232 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Golden-winged Warbler in Minneapolis [Saint Paul] on a given day, against under 5% in June–July and September–April, the lowest months. Those are among Minneapolis [Saint Paul]'s wettest months, with about 110 mm of rain a month against 20 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Golden-winged Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 18 cities where we can rate Golden-winged Warbler sightings, Minneapolis [Saint Paul] ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in San Diego (United States, under 5%) and Chicago (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Golden-winged Warbler is recorded against all the birds logged in Minneapolis [Saint Paul] (473 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.
