Black Swan
Lakes, rivers, swamps, and coastal waters across Australia. Also found in ornamental lakes in parks.
Hering griffon
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
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.
Hering griffon
Generally silent; hisses and grunts at carrion with other vultures. Gives low croaking 'arrr' near nest. At colonies produces cackling and grunting — not melodic vocalizations.

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.
Hering griffon
The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.
