All about Northern hake

Features & Description

The Long-tailed Duck, from its Latin name “Clangula hyemalis”, is a small brown, black and white duck with a wingspan of 82 cm.

Recognized by the long tail arrow (as with the Northern Pintail), this duck changes color with the season, with the head and neck turning from black to white in winter and the back from brown to gray.

The beak has a flesh-colored area.

Habitat (Biotope)

The Long-tailed Duck is a northern bird that enjoys the ponds and marshes of the Arctic tundra, and the coasts and waterways of the mountains.

Its winter migration takes it to lakes and lagoons.

Behavior & habits

The Long-tailed Duck has a gregarious instinct that can lead it to gather with several thousand other ducks.

Wintering at sea in large flocks, it’s a very restless and active bird, easily taking off and flying for brief chases low over the water, landing with a splash.

A diving duck, it loves to spend time underwater in search of crustaceans, small fish and insects.

Reproduction and immature

The Long-tailed Duck lines a small hollow area with grass to lay between 4 and 9 eggs.

Incubation lasts around 25 days.

The ducklings leave the nest as soon as they are born, and are able to fly after 40 days.

Cry or Voice

The male Long-tailed Duck emits a characteristically loud, yodeling, nasal call, both on parade and on migration.

In groups, this duck produces musical choruses reminiscent of distant bagpipes. A few nasal, low-pitched “gaks” punctuate briefer, plaintive “a-glèh-ah” versions.
