The Harlequin is a very endearing little Seaduck found in Arctic, Pacific and North Atlantic Oceans.  The male is a very colourful and attractive bird while, as with most ducks, the female is a bit drabber.  In Europe they only live in Iceland, but are a common visitor to harbours in Winter in Hokkaido - Shiranuka harbour had a good number of them present, and were reasonably confiding as ducks go.
