Habitat Comparison
Southern Pintail
Restricted to the sub-Antarctic Kerguelen and Crozet archipelagos. Inhabits freshwater streams, ponds, and coastal wetlands. Largely terrestrial for a duck; forages on land among tussock grasses.
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
Southern Pintail
Female produces a quiet, nasal quacking; male gives a soft whistle. Subdued vocalizations suit this sub-Antarctic island duck; calls are seldom heard and rarely documented.
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
Southern Pintail
Breeds in Iceland and high-Arctic Norway; winters on the coasts of northwestern Europe and the British Isles.
Blue-billed Teal
Breeds in Arctic and subarctic Eurasia; winters at sea in the North Atlantic and from western Europe to eastern Africa.

About These Birds
Southern Pintail
A small island duck found on the remote Kerguelen and Crozet archipelagos in the sub-Antarctic Indian Ocean. Closely related to Northern Pintail. Non-migratory island endemic; small population threatened by introduced predators and overgrazing by rabbits.
Blue-billed Teal
A small dark teal with blue-grey bill and legs, brown-streaked plumage, and fine pale spotting on the flanks. The most widespread teal in sub-Saharan Africa. Found on freshwater lakes and marshes. Highly nomadic; follows seasonal rainfall. Swims low in the water like a pochard.
