Habitat Comparison
Black Swan
Lakes, rivers, swamps, and coastal waters across Australia. Also found in ornamental lakes in parks.
Common Nightingale
Dense thickets, scrub, and undergrowth in deciduous woodland. Prefers areas with thick ground cover near water.
Song & Call Comparison
Black Swan
Gives a musical bugling 'boo-boo-boo' in flight and softer honking on water. Less vocal than Mute Swan; produces a baying call when alarmed. Wings whistle softly in flight.
Common Nightingale
Considered Europe's finest songster: an extraordinarily rich, loud, flute-like melody of bubbling trills, slow whistles, and a distinctive crescendo 'lu-lu-lu'. Sings day and night.

Black Swan
Australia, primarily in the southeast and southwest. Introduced populations in New Zealand, Japan, and western Europe.

About These Birds
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
Common Nightingale
夜莺（Luscinia megarhynchos）— 分布于欧洲和中亚，在非洲越冬。以夜间也能听到的复杂而丰富的歌声著称。
