Where does american Black Duck usually live？

The American black duck is endemic to eastern North America. In Canada, the range extends from northeastern Saskatchewan to Newfoundland and Labrador. In the United States, it is found in northern Illinois, Michigan, New Jersey, Ohio, Connecticut, Vermont, South Dakota, central West Virginia, Maine and on the Atlantic coast to North Carolina. The American black duck is a habitat generalist as it is associated with tidal marshes and present throughout the year in salt marshes from the Gulf of Maine to coastal Virginia. It usually prefers freshwater and coastal wetlands throughout northeastern America, including brackish marshes, estuaries and edges of backwater ponds and rivers lined by speckled alder. It also inhabits beaver ponds, shallow lakes with sedges and reeds, bogs in open boreal and mixed hardwood forests, as well as forested swamps. Populations in Vermont have also been found in glacial kettle ponds surrounded by bog mats. During winter, the American black duck mostly inhabits brackish marshes bordering bays, agricultural marshes, flooded timber, agricultural fields, estuaries and riverine areas. Ducks usually take shelter from hunting and other disturbances by moving to brackish and fresh impoundments on conservation land.
