The Harlequin Duck is a sea duck from Arctic waters. It is also called a Squeaker because of its mouse-like call.

The female Harlequin Duck, like most female ducks, is plainer and better-camouflaged. She has a white ear-spot and pale cheeks.
Its range includes coasts of Iceland, Greenland, Canada, northern USA, eastern Siberia and northern Japan.
It inhabits rocky coasts in winter and rivers and fast streams in the southern part of its range in summer.
