The black swan is native to Australia and Tasmania. These birds inhabit freshwater lakes, rivers, swamps, and marshes, though they may also be found in coastal areas. Their lifespan in the wild ranges from 10 to 15 years, in captivity they can live up to 40 years. Males weigh approximately 6–9 kg, and females weigh 4–7 kg. Their body length varies from 110 to 140 cm, with a wingspan ranging from 160 to 200 cm. Black swans form lifelong pair bonds. They typically breed in the summer, constructing nests from vegetation on the water’s surface or onshore. The female lays between 4 and 6 eggs, with both parents sharing incubation duties for 35–40 days. The young remain with their parents for around 9 months. Black swans are highly social and may gather in small groups during migration.
These swans are herbivorous, feeding primarily on algae and other aquatic and terrestrial vegetation. They may occasionally consume insects, mollusks, and small crustaceans. The black swan evolved in Australia and is the only swan species (Cygnus) with black plumage.
The black swan symbolizes rarity and unpredictability. In many cultures, particularly in Australia, it is considered a source of national pride and serves as an important symbol in art and literature. In European culture, it was long considered mythical until it was discovered in Australia by Dutch explorers in the 17th century.
According to the International Union for Conservation of Nature (IUCN), the black swan holds a conservation status of “Least Concern.”
