Ducks are migratory birds, so seasons follow federal frameworks set for each flyway, and states choose their dates within them.

Duck stamp
Hunters 16 and older need a Federal Duck Stamp to hunt waterfowl.
HIP
Every migratory bird hunter must register with the Harvest Information Program. It is free and helps agencies survey the harvest.
Nontoxic shot
Lead shot has been banned for waterfowl hunting since 1991. Steel, bismuth and tungsten shot are approved.
Plugged shotgun
Shotguns must be limited to three shells for migratory birds.
Dates, limits and rules change every year. Always check the current regulations.
