Mallard Anas platyrhynchos Family: Anatinae This is the most commonly seen duck in the United States. Mallards have a wide variety of habitat. They can be seen on lakes, rivers, streams, ponds, and marshes. They eat a variety of grasses and herbs. The Monument has few suitable habitats for Mallards so it is rare to see one at Jewel Cave. |
