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.
Garganey
Breeds on freshwater marshes, flooded meadows, and lake margins in Eurasia from Europe east to Siberia. Winters across sub-Saharan Africa, the Indian subcontinent, and Southeast Asia in wetlands of all kinds.
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.
Garganey
Male produces a distinctive mechanical rattle or craking sound; female gives a subdued quack. The rattling male call is unlike any other teal and immediately diagnostic.

Breeds across boreal and subarctic Canada and Alaska; winters in the southern United States, Mexico, and Central America.
Garganey
Breeds across the Palearctic; winters from western Europe and North Africa east through South Asia to Southeast Asia.
