Pure white face contrasting with a black crown and rear neck, chestnut-brown lower neck and breast, and finely barred flanks.
Size & weight
Length: 38-48 cm, Wingspan: 86-100 cm, Weight: 500-800 g
Voice — call & song
A very loud, clear, three-note whistle ('see-oo-wee') often given in flight or when disturbed.
Diet & foraging
Primarily vegetarian, feeding on seeds of aquatic plants, grasses, and cultivated grains like rice, supplemented with small aquatic invertebrates.
Habitat
Freshwater wetlands, shallow lakes, marshes, reservoirs, and flooded fields with abundant emergent vegetation.
Migration & movement
Mainly resident, though some populations undertake local or regional nomadic movements in response to rainfall and seasonal water availability.
Nesting & breeding
Nests are typically built on the ground hidden in tall grass or reeds, though they occasionally use tree cavities. Clutch size ranges from 6 to 12 eggs, incubated by both parents.
Similar species
Other whistling duck species, but the distinct white face combined with the chestnut neck makes the White-faced Whistling Duck unmistakable within its range.
Ecological significance
Acts as a seed disperser and plays a role in aquatic food webs by consuming seeds, aquatic vegetation, and small invertebrates.
Conservation status
Least Concern, with a stable population trend.
Observation tips
Look for them near shallow freshwater lakes, marshes, and flooded agricultural fields, often in large, vocal flocks. They are frequently active both day and night.
Interesting facts
Unlike many typical ducks, whistling ducks form strong, long-lasting pair bonds, and both parents share equally in incubating the eggs and raising the ducklings.
