A very distinct, loud, clear, three-note whistling call ('see-ui-ou') often given in flight or when disturbed.
Diet & foraging
Primarily vegetarian, feeding on seeds of aquatic plants, grasses, grains, and occasionally small aquatic insects and mollusks by dabbling or grazing on land.
Habitat
Shallow freshwater lakes, marshes, flooded grasslands, swamps, and agricultural fields with abundant emergent vegetation.
Migration & movement
Mainly resident or nomadic, undertaking localized seasonal movements in response to rainfall and water availability.

Ecological significance
Acts as a seed disperser and plays a role in nutrient cycling in wetland ecosystems through its foraging and feeding habits.
Conservation status
Least Concern, with a stable and widespread global population
Observation tips
Easily observed at freshwater wetlands, lakes, and marshes. They are often approachable at managed wildlife parks or reserves and frequently roost in large, noisy flocks near the water's edge.
Interesting facts
Unlike typical ducks, whistling ducks spend a considerable amount of time perched in trees and possess a more goose-like posture and social structure.
