Blue-billed duck

The blue-billed duck is a captivating small duck native to Australia, renowned for its striking appearance and distinctive behaviors. Male blue-billed ducks are characterized by their vivid blue bills, while females possess black feathers with brown-tipped edges. These ducks exclusively inhabit the temperate regions of Australia, residing in both natural and artificial wetlands. Regrettably, they are threatened by habitat degradation and water drainage.

First described by John Gould in 1836, the blue-billed duck is currently classified as Near Threatened by BirdLife International. Its scientific name, *Oxyura australis*, underscores its southern Australian origins. One of the duck’s most notable features is its stiff tail feathers, which, along with its strong feet, contribute to its excellent swimming and diving abilities. These ducks are largely aquatic, favoring deep freshwater swamps rich in dense vegetation. Their diet is omnivorous, but they particularly relish small aquatic invertebrates.

Regarding breeding, blue-billed ducks are known for their elusive nature and intricate courtship displays. They exhibit partially migratory behavior, with variable laying periods and clutch sizes. Conservation efforts are vital for these ducks, focusing on mitigating habitat loss and the impacts of water regulation to support their populations. In Victoria, the blue-billed duck is listed as threatened, while in New South Wales, it is recognized as vulnerable.
