The Black Swan, cygnus atratus, is a large waterbird native to Australia, easily distinguished by its mostly black plumage and striking red bill with a white band. It measures between 110 to 142 centimeters in length and has a wingspan of up to 2 meters, making it one of the larger members of the duck, goose, and swan family. Unlike its Northern Hemisphere relatives, the Black Swan features a unique body coloration, with the exception of white flight feathers that become visible in flight. Juveniles display a greyish hue, gradually darkening to black as they mature. The Black Swan's elegant appearance and contrasting colors have made it a symbol of beauty and mystery in various cultures.

Black Swans are highly adaptable, inhabiting a range of wetlands, including lakes, rivers, and estuaries, as well as artificial water bodies like ornamental lakes, where they can often be seen grazing on aquatic and adjacent terrestrial vegetation. They are social birds, frequently found in large flocks that can number in the hundreds. These swans are known for their monogamous breeding behavior, often reuniting with the same partner each season, and they exhibit a high degree of parental care.
The diet of the Black Swan is predominantly vegetarian, consisting of algae, aquatic plants, and grasses. They feed by dipping their long necks under the water to reach vegetation, and they will also graze on land. This diet is supplemented by small amounts of aquatic insects and crustaceans, especially during the breeding season to ensure adequate nutrition for the development of their eggs.
Reproduction in Black Swans is somewhat flexible, occurring in large colonies or isolated pairs depending on environmental conditions. They build large nests near the water's edge, where the female lays 4 to 8 pale green eggs. Both parents share incubation duties over a period of about 35 to 40 days. Cygnets are born with white down and are tended by both parents, often riding on their back for warmth and protection as they learn to swim and feed themselves.
The Black Swan is considered to be of Least Concern by conservation standards, thanks to its wide distribution and stable population. However, they can be affected by habitat destruction, pollution, and changes in climate that alter their wetland environments. Conservation efforts focus on the protection of wetland habitats and monitoring of populations to ensure the species remains abundant. The adaptability of the Black Swan to modified landscapes has also facilitated its success, allowing it to thrive in both natural and urban settings.
