The common shelduck (Tadorna tadorna) is a waterfowl species of the shelduck genus Tadorna.

Wintering is in temperate to subtropical regions.
The common shelduck was formally named by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Anas tadorna. Linnaeus largely based his description on "The Sheldrake or Burrough-Duck" that had been described and illustrated in 1731 by the English naturalist Eleazar Albin. The specific epithet comes from the French word Tadorne for this species, a name that was used by the French naturalist Pierre Belon in 1555. It may originally derive from Celtic roots meaning "pied waterfowl", essentially the same as the English "shelduck". Linnaeus specified the locality as Europe but restricted this to Sweden in 1761. The common shelduck is now placed in the genus Tadorna that was introduced in 1822 by the German zoologist Friedrich Boie. The species... Wikipedia →

Possible
About 30% of wildlife watchers report a Common Shelduck sighting in Kiskunság National Park on a given day, based on 305 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 222 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 60% of wildlife watchers report a Common Shelduck in Kiskunság National Park on a given day, against about 10% in June and August–September, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Common Shelduck sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 14
Of the 14 parks where we can rate Common Shelduck sightings, Kiskunság National Park ranks 4th at about 30%. The best odds are in Wadden Sea National Park (Germany, about 60%), Snowdonia National Park (United Kingdom, about 40%) and Camargue (France, about 30%). All parks ranked.
Same family: Anatidae
The closest relatives of the Common Shelduck that you can see in Kiskunság National Park (family Anatidae, Ducks, Geese, and Swans) are Greylag Goose (about 80%), Mallard (about 70%) and Eurasian Teal (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Shelduck is recorded against all the birds logged in Kiskunság National Park (305 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.
