King Eider

Somateria spectabilis

'King' is for the orange, crown-shaped knob on the male's bill, a name taken straight from Icelandic. Its scientific name, spectabilis, means 'worth seeing,' from the same root as 'spectacle.'

Somateria means 'woolly body,' for its thick down; spectabilis is Latin for 'showy' or 'remarkable.' 'Eider' comes from the Icelandic æður.
