The ruddy shelduck (Tadorna ferruginea) is a bird species in the family Anatidae. It is a distinctive waterfowl, 58 to 70 cm (23 to 28 in) in length with a wingspan of 110 to 135 cm (43 to 53 in). It has orange-brown body plumage with a paler head, while the tail and the flight feathers in the wings are black, contrasting with the white wing-coverts. It is a migratory bird, wintering in the Indian subcontinent and breeding in southeastern Europe and central Asia, though there are small resident populations in North Africa. It has a loud honking call.
The ruddy shelduck mostly inhabits inland water-bodies such as lakes, reservoirs and rivers. The male and female form a lasting pair bond and the nest may be well away from water, in a crevice or hole in a cliff, tree or similar site. A clutch of about eight eggs is laid and is incubated solely by the female for about four weeks. The young are cared for by both parents and fledge about eight weeks after hatching.
In central and eastern Asia populations are steady or rising, but in Europe they are generally in decline. Altogether, the birds have a wide range and large total population, and the International Union for Conservation of Nature has assessed their conservation status as being of least concern.

Rare
Under 5% of wildlife watchers report a Ruddy Shelduck sighting in Doñana National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 212th most-seen of the 234 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Ruddy Shelduck in Doñana National Park on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Ruddy Shelduck sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
17th of 18
Of the 18 parks where we can rate Ruddy Shelduck sightings, Doñana National Park ranks 17th at under 5%. The best odds are in Kaziranga National Park (India, about 60%), Chitwan National Park (Nepal, about 50%) and Bale Mountains National Park (Ethiopia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Ruddy Shelduck is recorded against all the birds logged in Doñana National Park (18 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.
