The sex of the birds shown below was not determined by any distinguishing features, but by their behaviour. They were found resting in the same spot on multiple occasions over the course of weeks, and the location turned out to be close to a nest, presumably with a female in it, at Lake Herdsman, Perth, WA, shown below.

Breeding information |
Breeding season: Aug - Nov | Eggs: 6 - 8 | Incubation period: 26 days | Fledging age: N/A |
Pink-eared Ducks breed mostly in the south-eastern quarter (inland, west of the Great Dividing Range, mostly to the East of the NSW/SA border) and in the south-western corner of the Australian continent. Although Pink-eared Ducks preferably breed in the southern spring, they can in principle breed any time of the year, usually after a big rain event (usually after floods, when the water starts receding).
Like other ducklings, young Pink-eared Ducks are precocial, leaving their nest at a young age, to be led by their mother until they can fly.
Nest building: ? | Incubation: Female | Dependent care: Female |

Nest |
"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal] |
Type: Basket | Material: Downy feathers | Height above ground: 0.5 - ? m |
Usually the nest will be in an open hollow, usually in the trunk of an old, dead tree, less exposed than the nest shown here. The only material used is an abundance of feathers that can totally cover the eggs.

Behaviour |
Social behaviour: Communal | Mobility: Dispersive | Elementary unit: Large flock |
Pink-eared Ducks are often found in flocks, with up to hundreds of birds resting or flying together. They often roost together with other ducks or waders or other species of aquatic birds.
Pink-eared Ducks can often be seen going around each other in circles,
presumably to create a vortex to trap prey

Many, mostly land-based, bird species have a staggered moult of their wing feathers, thus ensuring that at any one point in time only a few feathers are missing, which enables them to continue flying throughout a moult.
Other, mostly aquatic, bird species that live in habitats in which they are safe from predators, allow themselves the luxury of a quicker, more radical moult, in which basically all flight feathers are replaced at once. Such a full wing moult will render birds flightless for a number of weeks.

We have seen Pink-eared Ducks associating with Grey Teals on several occasions (see e.g. above the photos of flocks in flight).
Occasionally, we have observed Pink-eared Duck swimming in two parallel lines in opposite directions, then often paddling in circles around one another in pairs. This may have been a way to create waves or eddies while filter-feeding.

directions, then circling around each other in pairs while

Food, Diet |
Pink-eared Ducks are specialists in collective filter-feeding;
by swimming in circles they create vortices in which material is
trapped that they then take in (photo courtesy of M. Eaton)
[Gratton, QLD, August 2017]
Pink-eared Ducks have two basic feeding techniques; "vortexing",
as also shown above...
