The legal hunting dates for duck season vary by state, as well as by the type of duck being hunted. Most duck hunting seasons begin in the fall and end in the winter.
It is best to research the dates when ducks can be hunted legally in each state or area. There are a number of websites that offer this information, such as WhenIsDuckSeason.com. Each state has a hunting-regulations department; for example, it might be called the Department of Fish and Wildlife or the Department of Natural Resources. Finding that department's website or contact information provides the most accurate and reliable information.
