"Every winter, American Black Ducks migrate to the Bay region where food—seeds, grasses, small invertebrates—are abundant. However, over the last century, their numbers have decreased dramatically, as the Bay’s marshes and wetlands have disappeared. Scientists are tracking populations of these shy, native waterfowl, to learn more about their health and that of the damp and remote habitats they frequent. Armed with this understanding, experts are also now using it to focus their conservation and restoration resources and efforts on the Bay’s marshes and wetlands."
