Ring-necked Duck


The ring-necked duck nests in boggy marshes or small lakes, surrounded by sedges, cattails and water lilies. They mate in early April, and most eggs (about six to twelve per nest) are laid a month later. The ducklings grow fast, and fly in about 50 days after hatching.


They eat only plant material, particularly wild rice and sago pond weed.
