Habitat Comparison
Falcated Duck
Breeds along rivers and lake shores in Siberian taiga and meadows. Winters on freshwater lakes and rivers in China, Japan, and South Korea. Sensitive to hunting pressure and wetland drainage.
Blue-billed Teal
Freshwater lakes, marshes, pans, and flooded grasslands across sub-Saharan Africa from Senegal and Sudan south to the Cape. Nomadic; follows seasonal rains. Common but easily overlooked among reed beds.
Song & Call Comparison
Falcated Duck
Male gives a soft, whistled whi-ooo note; female produces a low, grunting quack. The male's haunting whistle is one of the more melodic sounds of East Asian wetlands in winter.
Blue-billed Teal
Male utters a soft, teal-like peep; female gives a muted quack. Pairs call quietly in dense papyrus; soft contact calls help birds maintain proximity in thick African marsh vegetation.
Geographic Range & Migration
Falcated Duck
Nomadic across the interior wetlands of Australia; moves widely in response to flooding and drought conditions.
Blue-billed Teal
Breeds in Arctic and subarctic Eurasia; winters at sea in the North Atlantic and from western Europe to eastern Africa.
