The pink-eared duck is a species of duck found in Australia.
Region
Australia
Typical Environment
Widely distributed across mainland Australia, especially in the arid and semi-arid interior. It favors shallow, nutrient-rich wetlands including floodplains, temporary lakes, billabongs, sewage ponds, and farm dams. The species is highly nomadic, moving long distances in response to rainfall and flooding. It also occurs in coastal lowlands and occasionally on Tasmania when conditions suit. Breeding is strongly tied to the availability of ephemeral waterbodies.

Also called the zebra duck for its striking barred flanks, the pink-eared duck is a highly specialized filter-feeder with a broad, fringed bill. It is nomadic across Australia, tracking rainfall to ephemeral wetlands. Pairs often create cooperative feeding whirlpools that concentrate plankton. The rosy “ear” patch is most noticeable on adults and can be subtle at distance.

Temperament
social and wary
Flight Pattern
short rapid wingbeats; fast low flight over water
Social Behavior
Often seen in pairs or small to large flocks, sometimes associating with other duck species. Breeding is opportunistic after heavy rains; pairs are monogamous for the season. Nests are typically in tree hollows or dense vegetation near water, lined with down. Clutches are moderate in size, and both parents attend the brood.
Migratory Pattern
Nomadic
Song Description
Generally quiet; emits soft whistling notes and gentle grunts, especially during courtship. Contact calls are thin and high, with low chatter in flocks.
Plumage
Boldly barred flanks and body with fine brown-and-white zebra-like striping; darker crown and nape with pale face and contrasting mask.
Diet
Specialized filter-feeder taking planktonic crustaceans, insect larvae, small mollusks, and algae, along with some seeds and detritus. The spatulate bill with dense lamellae sifts fine particles from surface and shallow water. Birds often feed in pairs or small groups, creating swirling ‘pinwheels’ that concentrate food. They also skim and scythe side-to-side along calm water.
Preferred Environment
Shallow, calm, nutrient-rich waters such as floodplains, ephemeral lakes, sewage ponds, and billabongs. Frequently feeds along vegetated margins and open shallows with soft substrates.
