Habitat Comparison
Labrador Duck
Historically inhabited sandy coastal bays, estuaries, and mussel beds from Labrador to the mid-Atlantic United States. Extinct since 1878. Nesting grounds never confirmed; likely bred in Labrador.
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
Labrador Duck
Extinct (EX). No recordings exist. This North American scoter relative likely gave a quiet, grunting call during display based on the bill morphology suggesting possible unusual vocalizations.
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
Labrador Duck
Formerly along the eastern coast of North America from Labrador to Chesapeake Bay. Extinct by 1878; last specimen shot in New York.
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
Labrador Duck
An extinct sea duck from eastern North America; the first North American bird to go extinct after European contact. Males had boldly contrasting black-and-white plumage with an unusual flattened soft-edged bill adapted for filter-feeding on mussel beds. Last confirmed sighting in 1878.
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.
