Waterfowl managers are concerned about losing natural habitats and how it affects waterfowl populations. Researchers studied how breeding ducks use cultivated wild rice fields in Minnesota. They found that mallards, teal, and shovelers were the most common breeding ducks in the area. Nesting success was around 20%, with an average of 10 eggs per nest. Survival of ducklings was 42%. The study estimated about 999 ducklings fledged per year in the study area. To help increase duckling survival, techniques like preserving nesting cover and controlling predators should be considered.
