Canvasback (Aythya valisineria) - 13Dec2015

The Canvasback is the largest duck in North America, and probably the best.  It's latin name comes from the fact that its primary diet on breeding grounds up north is Vallisneria americana which is an aquatic plant.  It's common name is surprisingly intuitive, the white back is the color of a blank canvas.  However, I call it by a more affectionate name.... a  Carbunkled Snorfblatt.
