Black Swan

01 · Identification

How to tell it apart

The Black Swan is a massive, soot-black waterbird, measuring up to 1.4 metres with a two-metre wingspan. While appearing entirely dark at rest, it reveals bold, white flight feathers when its wings are spread. The exceptionally long, slender neck is often held in a graceful S-curve. Its most striking feature is a bright red bill with a pale subterminal band and tip, contrasting with dark grey legs. Males are slightly larger with straighter bills, while juveniles are a dusty grey-brown with pale feather fringes. The primary call is a far-reaching, musical bugle or trumpet, frequently heard from birds in flight. When defending a nest, they produce sharp whistles, and their rhythmic wingbeats create a distinctive metallic whistling hum. Highly nomadic, these swans move across the Australian continent in response to unpredictable rainfall, often congregating in massive flocks. They are primarily herbivorous, foraging by grazing on the surface, reaching deep underwater, or upending to reach submerged plants and algae. On the water, they may lift their wing feathers in a ruffled, arched display known as busking. In flight, they move in V-formations or long lines with slow, fluid wingbeats. They frequent a wide range of habitats, from large freshwater lakes and brackish swamps to tidal mudflats and urban parklands. During the post-breeding moult, they become flightless and retreat to deep, open bodies of water. At a distance or in low light, they may be confused with the Magpie Goose, but the Black Swan is distinguished by its significantly longer neck, all-black torso, and slower wingbeats.
