Habitat Comparison
Brent Goose
Breeds on high-Arctic tundra; winters on estuaries, coastal mudflats, saltmarshes, and sea-grass beds along Atlantic and Pacific coastlines. One of the most strictly coastal wintering geese.
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
Brent Goose
A low, guttural 'rronk' or 'ronk-ronk' from flocks. Soft nasal calls in feeding groups. A subtle, understated call for a goose — less loud than most Anser geese.
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.
Geographic Range & Migration
Brent Goose
Breeds across boreal and subarctic Canada and Alaska; winters in the southern United States, Mexico, and Central America.

About These Birds
Brent Goose
A small dark-bodied goose with a black head and neck, small white neck patches, and pale grey belly. Migrates between high-Arctic breeding grounds and temperate coastal wintering areas. Feeds on eel-grass and saltmarsh vegetation in winter. Three subspecies differ in belly coloration.
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.
