The white-winged duck or white-winged wood duck (Asarcornis scutulata) is a large species of duck, formerly placed in the genus Cairina with the Muscovy duck (Cairina moschata) and considered allied to the dabbling ducks. However, two genetic studies have indicated that the anatomical similarity to the Muscovy duck is deceiving, with the species appropriately placed in a monotypic genus, as Asarcornis scutulata; it proved evolutionarily closest to a clade containing the diving duck genera Netta and Aythya, while Cairina resolved as close to the genus Aix in a very different part of the family tree.
This is one of the largest living species of duck next only to the steamer ducks which are heavier. The Muscovy duck also attains sizes that nearly rival the white-winged duck, but may average a bit smaller in a wild state. Length is 66–81 cm (26–32 in) and wingspan is 116–153 cm (46–60 in). Males weigh 2.94–3.9 kg (6.5–8.6 lb), while females weigh 1.95–3.05 kg (4.3–6.7 lb). The most noticeable feature on adult birds is the dark body contrasting with a whitish head and neck. Males have a mostly dull yellowish bill, blackish mottling on the head and upper neck, white lesser... Wikipedia →

With luck
About 10% of wildlife watchers report a White-winged Duck sighting in Way Kambas National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 144th most-seen of the 205 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August and October
In those months about 20% of wildlife watchers report a White-winged Duck in Way Kambas National Park on a given day, against under 5% in May and July, the lowest months. Those are among Way Kambas National Park's driest months, with about 130 mm of rain a month against 370 mm in March. November to February have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-winged Duck sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Way Kambas National Park, in our data
Way Kambas National Park is the only park on Wallace's Line with enough records to rate White-winged Duck sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-winged Duck is recorded against all the birds logged in Way Kambas National Park (27 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.
