The American wigeon (Mareca americana), also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to Anas, this species is classified with the other wigeons in the dabbling duck genus Mareca. It is the New World counterpart of the Eurasian wigeon.
The American wigeon was formally described in 1789 by German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other ducks, geese, and swans in the genus Anas and coined the binomial name Anas americana. Gmelin based his description on Edme-Louis Daubenton's hand-colour plate of "Le Canard Jensen, de la Louisiane" and Thomas Pennant's description of the "American wigeon" in his Arctic Zoology. Pennant had been sent a specimen from New York. The American wigeon is now placed with the Eurasian wigeon and three other dabbling ducks in the genus Mareca that was introduced in 1824 by the English naturalist James Francis Stephens. The name of the genus comes from the Portuguese word Marréco for a small duck. The species is considered to be monotypic: no subspecies are recognised.

With luck
About 10% of wildlife watchers report an American Wigeon sighting in Portland on a given day, based on 5,703 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 230 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November and December
In those months about 30% of wildlife watchers report an American Wigeon in Portland on a given day, against under 5% in May to August, the lowest months. Those are among Portland's wettest months, with about 230 mm of rain a month against 10 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most American Wigeon sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
13th of 38
Of the 38 cities where we can rate American Wigeon sightings, Portland ranks 13th at about 10%. The best odds are in Anchorage (United States, about 60%), Ciudad Juárez (México, about 50%) and Mesa (United States, about 40%).
GBIF citizen-science records
It is estimated from how often the American Wigeon is recorded against all the birds logged in Portland (5,703 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.
