The ducks include the mallard, black duck, canvas-back and red-head; the Canadian goose, the snowy goose and the blue goose also appear during the migrating seasons.
Here, too, breed many species of ducks, the mallard, gadwall, baldpate, three species of teal, shoveler, pintail, hooded mergansers, and Canada geese; other ducks and geese are migrants only.
