Mandalay National Wildlife Refuge conserves and protects freshwater marshes in western Terrebonne Parish in south–central Louisiana. The refuge is a top priority wetland conservation project of the Gulf Coast Joint Venture of the North American Waterfowl Management Plan, as refuge marshes are important feeding and resting places for waterfowl in the Mississippi Flyway. Thousands of migratory waterfowl including mallards, blue and green-winged teal, gadwalls, widgeon, and mottled ducks visit the freshwater marshes each year. Forested areas provide critical spring and fall habitat for neotropical migratory birds. Bald eagles forage along refuge waterways and marshes between October – May.
