Habitat Comparison
Höckerschwan
Lakes, slow rivers, estuaries, and coastal lagoons. Often associated with parks and ornamental waters in Europe.
Freckled Duck
Dense inland freshwater swamps, tea-tree bogs, and reedy lakes across southern and inland Australia. Highly nomadic; follows ephemeral inland flooding. Key breeding sites in Murray-Darling Basin swamps.
Song & Call Comparison
Höckerschwan
Despite its name, not truly mute: gives hissing snorts and low grunting when threatened. Wings produce a loud rhythmic whistling throbbing sound in flight.
Freckled Duck
Soft, nasal 'quacking' and grunting sounds. Considered a quieter, more secretive duck than most. Males give a soft wheeze; females give low quacks. Not vocal by duck standards.

Höckerschwan
Native to Europe and western Asia. Introduced to North America, South Africa, Australia, and New Zealand.
Freckled Duck
Breeds in the sub-Arctic and boreal regions of North America; winters inland and coastally across the southern United States.

About These Birds
Höckerschwan
Der Höckerschwan gehört zu den schwersten flugfähigen Vögeln; Männchen können bis zu 14 kg wiegen. Trotz seines englischen Namens („Mute Swan“, stummer Schwan) ist er keineswegs stumm und gibt zischende, grunzende und schnaubende Laute von sich. Höckerschwäne gehen lebenslange Paarbindungen ein, und ihre aggressive Verteidigung des Brutreviers ist bekannt.
Freckled Duck
An unusual Australian duck with dark brown plumage densely speckled with small pale spots. Considered a living fossil with no close relatives—placed in its own subfamily. Males have a red base to the bill in breeding season. Found in inland Australia; highly nomadic following rainfall.
