Habitat Comparison
American Black Duck
Freshwater and brackish wetlands in eastern North America from Atlantic Canada south along the coast to Georgia. Breeds in northern bogs and wetlands. Winters on coastal marshes, estuaries, and freshwater lakes.
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
American Black Duck
Female produces a loud, deep quacking series; male gives a low, raspy grunt. Voice is deeper and huskier than a Mallard; pairs call powerfully across northeastern North American wetlands.
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.
