The mallard is one of the most common species of waterfowl in the world; however, it is also one of the most heavily hunted species in North America. Consequently, successful management of mallards for recreational harvest by waterfowl hunters requires information on key vital rates like nest success and adult survival and an understanding of how vital rates vary with things like habitat conditions. Dr. Bruce Dugger, his students, and colleagues have studied various aspects of mallard biology during winter, including adult survival and movements, and during the breeding season, including factors that influence the likelihood of nesting, nest success, adult survival, and duckling survival. Results have been used by states and regional habitat joint ventures to improve habitat and population models for mallards.
