==Etymology==

The word "duck" originates in 14th century Old English, with the word ''dūce''; a verb meaning lowering one's head or body to avoid something.  This evolved into the Middle English word ''douken'', which in turn became the word used today.<ref>http://www.merriam-webster.com/dictionary/duck</ref>  The word also describes the actions of many of the birds themselves, as they suddenly dip their heads into the water when searching for food, leaving their rear parts upended above the water's surface.
