The wood duck or Carolina duck (Aix sponsa) is a partially migratory species of perching duck found in North America. The male is one of the most colorful North American waterfowls. The wood duck was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Anas sponsa. Linnaeus based his account on the "summer duck" from Carolina that had been described and illustrated by the English naturalist Mark Catesby in the first volume of his The Natural History of Carolina, Florida and the Bahama Islands that was published between 1729 and 1731. Linnaeus specified the type locality as North America but this has been restricted to Carolina following Catesby. The wood duck is now placed together with the mandarin duck in the genus Aix that was introduced in 1828 by the German naturalist Friedrich Boie. The species is monotypic: no subspecies are recognised. The genus name is an Ancient Greek word for an unidentified diving bird mentioned by Aristotle. The specific epithet sponsa is Latin meaning "bride" (from spodere meaning "pledge").

With luck
About 10% of wildlife watchers report a Wood Duck sighting in Philadelphia on a given day, based on 1,892 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Wood Duck in Philadelphia on a given day, against under 5% in November to February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Wood Duck sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
19th of 46
Of the 46 cities where we can rate Wood Duck sightings, Philadelphia ranks 19th at about 10%. The best odds are in Minneapolis [Saint Paul] (United States, about 40%), Vancouver (Canada, about 30%) and Montreal (Canada, about 20%).
GBIF citizen-science records
It is estimated from how often the Wood Duck is recorded against all the birds logged in Philadelphia (1,892 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.
