They are similar species with some differences. These birds are omnivorous. This means they eat aquatic invertebrates, as well as, plants and fruits. They spend most of their lives in the water. During their non-breeding season, they are seen in freshwater lakes and dams in large flocks. During the breeding season, these mating birds flock to densely vegetated, deep swamps of freshwater.

In the non-breeding season, younger ducks usually flock in hundreds in open lakes and dams, usually far away from the shore. This happens during autumn and winter. During the breeding season, adults prefer densely vegetated, deep, freshwater swamps. They are also known to be found in rivers and billabongs, which are saline water bodies, but it is very rare.

The breeding seasons for these birds can vary, but it is usually from August to November. Males have a complex mating ritual. They tend to breed in unfrequented freshwater swamps with dense vegetation. They make their nests over water, mostly in cumbungi beds like Typha and bullrush. They use dead Typha leaves to make their nests. These ducks are polygamous in nature and only come together as a pair for short bouts of time. They stay as a pair during mating and egg-laying. Females lay about four to six eggs in a single clutch, but the numbers of the eggs may vary from 3-13. Larger clutch sizes may mean that two females laid eggs in one nest. They incubate the eggs for about 27 days. These ducks are partially migratory and they move from mating grounds to lakes and rivers in the non-breeding season. The young only remain in the nest for a day before their mother leads them out and they become independent at a young age. They become almost the same size as their parents and within a year they acquire adult plumage.

What is their conservation status?

The conservation status of blue-billed duck birds is listed as Not Threatened in the International Union for Conservation of Nature Red List. This means that they have a safe population and are not Endangered. Their population trend is also stable and not declining, which is good news.
