Pink-eared Duck

Identification

The pink-eared duck is an unmistakable species, measuring 38–40 cm in length. Its most striking features include a brown back and crown contrasted with black and white barred sides and distinctive black eye patches on an otherwise white face. The bird's most famous characteristic—the pink spot in the corner of its head pattern—is only visible at close distance, which explains why early observers favored the alternative name "zebra duck," more readily apparent from the bird's bold barring pattern. The large, spatulate bill resembles that of the Australasian shoveler, though the pink-eared duck is considerably smaller. Juveniles are slightly duller in plumage but otherwise similar in appearance to adults.

Range & habitat

The pink-eared duck is widely distributed throughout Australia and is highly mobile, appearing wherever standing water exists. These ducks show a particular preference for dry inland regions where annual rainfall rarely exceeds 15 inches (380 mm). Their nomadic nature means they can turn up in unexpected locations, always following the availability of water that sustains their specialized diet.

Behaviour & diet

Pink-eared ducks are filter feeders dependent on plankton, crustaceans, mollusks, and insects. Their specialized bill features pliable mandibular flaps that channel water to allow efficient straining of algae and other microscopic organisms. One of their most remarkable feeding behaviors is vortexing, in which two ducks spin about a central point with the head of one opposite the tail of the other, creating a gyrating water column that concentrates food in the center. Breeding is stimulated by the drying and refilling of pools, which promotes increased levels of organic material in the water. During favorable years, large numbers of these ducks concentrate in shallow flood plains, but when environmental conditions are unsuitable, reproduction may be completely curtailed.

Best time & places to see it

Pink-eared ducks are best located by finding suitable water sources, particularly in inland Australian regions. The timing of sightings is unpredictable due to the species' nomadic nature and dependence on rainfall patterns. Shallow flood plains and standing water bodies in dry regions offer the best opportunities for encountering these birds, especially following periods of rain that create the conditions necessary for their breeding and feeding.

Photography tips

Photographing pink-eared ducks requires patience and attention to detail. To capture the namesake pink ear spot, you will need to get relatively close to the bird, as this feature is only visible at close range. The striking black and white head pattern and barred sides provide excellent contrast for photography. Observing their fascinating vortexing behavior offers unique photographic opportunities, though capturing this coordinated feeding display requires anticipation and quick reflexes.
