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.
Muscovy Duck
Tropical and subtropical lowland forest near rivers, lakes, mangroves, and wetlands from Mexico through Central America to Peru, Bolivia, and Uruguay. Common near forest-edge water. Feral populations worldwide.
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.
Muscovy Duck
Males are nearly silent; females give a raspy, low 'grrrr' hiss when threatened. Domesticated birds familiar worldwide but wild birds are surprisingly quiet and secretive.
