The relationships between canvasback (Aythya valisineria) breeding, wintering, and harvest areas were examined by analyzing banding data.

The migration of the canvasback duck during the winter months is observed at the Lake of the Lillies and Twilight Lake. The preferred areas and the vegetation in these areas is noted.

"The Canvasback Aythya valisineria is a wild duck that is found only in North America. It is a favorite of hunters, as it is delicious to eat if it has itself eaten the right food"--p. [2].
