Aythya Valisineria Views
The species name of the Canvasback, Aythya valisineria, comes from Vallisneria americana, or wild celery, whose winter buds and rhizomes are its preferred food during the nonbreeding period. The duck's name is based on early European inhabitants of North America's assertion that its back was a canvaslike color. The French call the canvas back the Morillon lagrave; dos blanc, and the Spanish refer to it as Pato coacoxtle.
