Before the end of the year (2011) John Mellin the Agency avid bird watcher saw 2 canvasbacks in the Park ponds. Very excited since we get to add a new duck to our lists!!
- 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. (http://www.allaboutbirds.org/)
