The Moveable Feast

During spring migration, waterfowl need an abundance of food to return to the breeding grounds in good condition.

What's the bottom line? Our research suggests that to meet the energetic demands of female ducks during spring migration, managers should provide a variety of shallow- and deep-water wetlands rich in both seeds and invertebrates sought by feeding hens. As you move north up the flyway, a greater emphasis should be placed on invertebrate production to meet the dietary preferences and needs of female ducks. Conservation practices and policies that protect existing habitat and improve water quality in wetlands, especially in the Upper Midwest, will help provide a more bountiful spring buffet for migrating waterfowl. And in doing so, we can help ensure that waterfowl will have a better chance of successfully nesting and raising young when they return to the breeding grounds later in spring.


Black Duck Migration Study Completed

Spring migration patterns and ties between breeding and wintering grounds were the focus of a parallel study on black ducks conducted by Ducks Unlimited and partners in the Atlantic and Mississippi flyways. In this research project, 68 hen black ducks were trapped and fitted with satellite transmitters across Ohio, Virginia, Delaware, New Jersey, and New York. These birds were then monitored throughout their annual cycle to determine their migration routes and breeding and wintering areas.

This work confirmed that most black ducks wintering east of the Chesapeake Bay breed in eastern Quebec and the Maritime Provinces, while black ducks that winter to the west of the bay breed farther inland, primarily in Ontario. During the winter, most hens remained close to their trapping location, indicating that the birds are faithful to particular wintering areas. The study also found that for black ducks, spring migration is more protracted, and the birds make more stops while migrating in spring than in fall. These results further support the need to provide high-quality spring migration habitat where black ducks and other waterfowl can acquire nutrients as they move north to breed.
