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.
Wandering Whistling-duck
Tropical freshwater marshes, flooded grasslands, swamps, and lake margins from the Philippines and Indonesia through Papua New Guinea to northern and eastern Australia. Nomadic following wet season flooding.
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.
Wandering Whistling-duck
A soft whistle 'whi-whi-whi' in flight. Less vocal than other whistling-ducks; flocks tend to be quieter. Given at dawn and dusk during flight to roosting or feeding areas.
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.
Wandering Whistling-duck
Breeds in Arctic and subarctic regions; winters at sea around the Antarctic pack ice, one of the longest migrations known.

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.
Wandering Whistling-duck
O parreco-vagabundo é um pato assobiadeiro encontrado da Indonésia e Filipinas à Austrália. Tem a coloração castanho-avermelhada típica dos parrecos com flancos largamente barrados de castanho-escuro e branco. Habita zonas húmidas de água doce, incluindo lagos, pântanos e planícies inundadas tropicais. É gregário e frequentemente mistura-se com outras espécies de parrecos. Os bandos podem ser muito numerosos durante as estações não reprodutoras.
