Federal hunting laws set nationwide rules in four main areas: migratory birds, endangered species, wildlife trafficking, and activity on federal lands. Everything else, including seasons and bag limits for resident game like deer, elk, and turkey, is handled by your state. When federal and state rules cover the same ground, you follow whichever is stricter. Federal rules are the floor. States can build above that floor but cannot dig below it.
Migratory Birds
The Migratory Bird Treaty Act of 1918 is the core of federal hunting regulation. It implements four international treaties, with Canada, Mexico, Japan, and Russia, protecting bird populations that cross borders.1U.S. Fish & Wildlife Service. Migratory Bird Treaty Act of 1918 It covers ducks, geese, doves, woodcock, rails, cranes, and hundreds of other species. Taking any protected migratory bird without federal authorization is illegal.2Bureau of Ocean Energy Management. Migratory Bird Treaty Act (MBTA)
Each year the U.S. Fish and Wildlife Service issues framework regulations that set maximum season lengths and the highest allowable bag and possession limits for each species. States then pick their specific opening and closing dates and bag limits within those federal ceilings. A state can be stricter, never more generous.3U.S. Fish and Wildlife Service.

Penalties are meaningful. A standard MBTA violation is a federal misdemeanor carrying up to $15,000 in fines and six months in jail. Knowingly taking a migratory bird with intent to sell it is a felony with up to $2,000 in fines and two years in prison.4Office of the Law Revision Counsel. 16 USC 707 – Violations and Penalties The misdemeanor is a strict liability offense for direct takings. The government does not have to prove you intended to break the law.
Federal Duck Stamp and HIP Registration
Beyond your state license, migratory bird hunters need two federal items that catch new hunters off guard.
Every waterfowl hunter age 16 or older must carry a valid Federal Migratory Bird Hunting and Conservation Stamp, the “duck stamp.” You sign across the face of the physical stamp in ink, or you can carry an electronic version. It applies to the taking of migratory waterfowl, not other migratory birds like doves or woodcock.5Office of the Law Revision Counsel. 16 USC 718a – Prohibition on Taking Almost all revenue from stamp sales goes to acquiring and protecting wetland habitat in the National Wildlife Refuge System.6U.S. Fish & Wildlife Service. Federal Duck Stamp Program Fact Sheet
If you hunt any migratory game bird species, you must register with the Harvest Information Program before heading into the field. HIP covers a broader list than the duck stamp: ducks, geese, coots, doves, woodcock, rails, snipe, sandhill cranes, band-tailed pigeons, and gallinules all trigger the requirement. You register through your state wildlife agency when you buy your license, and you need to carry proof of HIP registration while hunting. Hunting migratory birds in more than one state means registering separately in each.7U.S. Fish & Wildlife Service. Migratory Bird Harvest Surveys – What We Do
Prohibited Methods
Federal rules ban several methods for migratory game birds nationwide, no matter what your state allows for other game.
Your shotgun cannot hold more than three shells total. If the magazine capacity exceeds three, you need a permanent plug that can only be removed by disassembling the gun. Hunting over bait is also prohibited. You cannot place grain, salt, or other feed to attract migratory birds, and you cannot hunt in an area you know or should know has been baited. This trips up plenty of hunters: even if someone else spread the bait and you had no part in placing it, hunting the area once you know about the bait is still a violation.8eCFR. 50 CFR 20.21 – What Hunting Methods Are Illegal
When hunting ducks, geese (including brant), swans, or coots, you cannot use lead shot. Federal regulations require nontoxic shot, and each approved shot type must contain less than one percent residual lead. Steel is the most common and affordable option, and the approved list also includes bismuth-tin, various tungsten alloys, and copper-based shot.9eCFR. 50 CFR 20.21 – What Hunting Methods Are Illegal The rule exists because waterfowl ingest spent pellets from the bottom of wetlands, and lead is toxic when swallowed. It applies only to waterfowl and coots, not to upland migratory birds like doves or woodcock, though some states extend the lead ban more broadly on their own.
The Airborne Hunting Act makes it a federal crime to shoot at or harass any bird, fish, or other animal from an aircraft, including using an aircraft to herd or drive wildlife toward hunters on the ground. Violations carry fines and imprisonment.10GovInfo. 16 USC 742j-1 – Airborne Hunting State wildlife agencies can request federal exemptions for management purposes like aerial predator control. No exemption exists for recreational hunters.
Endangered Species
The Endangered Species Act of 1973 flatly prohibits the “take” of any species listed as endangered. The law defines take to include harassing, harming, hunting, shooting, wounding, killing, trapping, or capturing a listed animal.11GovInfo. 16 USC 1532 – Definitions The ban applies to everyone in the United States, on any land regardless of ownership, and overrides any state law or permit that might otherwise allow the activity.12U.S. Fish & Wildlife Service. Endangered Species Act Section 9 – Prohibited Acts>
The practical impact is that you need to know which species in your area are listed. Shooting a listed species because you misidentified it is not a defense. The Fish and Wildlife Service maintains the current list of endangered and threatened wildlife, and checking it before hunting unfamiliar territory is worth the few minutes. Threatened species are protected too, with specific rules that vary by species under regulations issued through Section 4(d) of the Act.
Penalties are severe. A knowing violation of the core prohibitions can bring a criminal fine up to $50,000 and up to one year in prison. Civil penalties reach $25,000 per violation for knowing conduct, with lower tiers down to $500 for unknowing violations.13U.S. Fish & Wildlife Service. Endangered Species Act Section 11 – Penalties and Enforcement
The Lacey Act
The Lacey Act is the federal government’s main tool against illegal wildlife trade. Originally enacted in 1900 and amended significantly since, it makes it a federal offense to trade in wildlife taken in violation of any other law: federal, state, tribal, or foreign.14Office of the Law Revision Counsel. 16 USC 3372 – Prohibited Acts
The Act’s real teeth show when it federalizes a state-level violation. If you exceed a state bag limit and then transport those animals across state lines, particularly with any intent to sell, you have committed a federal crime. A knowing violation involving the sale or purchase of illegally taken wildlife worth more than $350 carries up to $20,000 in fines and five years in prison. Without a commercial motive, a knowing violation with due-care culpability can bring up to $10,000 in fines and a year of imprisonment.15Office of the Law Revision Counsel. 16 USC 3373 – Penalties and Sanctions
Federal authorities can also seize property used in violations. Illegally taken wildlife is subject to forfeiture regardless of whether anyone is convicted. For felony violations, the government can pursue forfeiture of vehicles, boats, aircraft, and equipment, provided the owner knew or should have known the property would be used in the violation.16eCFR. 7 CFR 356.1 – Property Subject to Forfeiture Procedures
Hunting on Federal Lands
The federal government manages roughly 640 million acres, and the rules for hunting on it depend on which agency manages the parcel. In every case you still need valid state licenses and must follow state seasons and bag limits. Federal rules layer on top of state requirements, not in place of them.
BLM and National Forest Land
Bureau of Land Management and Forest Service lands are the most accessible for hunters. BLM lands are open to hunting unless a specific area has been closed, and the agency asks hunters to check with local field offices about closures and restrictions before a trip.17Bureau of Land Management. Hunting and Fishing National forests work similarly: hunting is allowed and regulated by state law, though individual forests can close areas for safety or resource management.18U.S. Forest Service. Hunting Neither agency typically requires an additional federal permit for hunting.
National Wildlife Refuges
National Wildlife Refuges are managed by the Fish and Wildlife Service, and the rules are tighter. Federal law designates hunting as a “priority general public use” of the refuge system, but each individual refuge decides whether hunting is compatible with its conservation mission.19Office of the Law Revision Counsel. 16 USC 668dd – National Wildlife Refuge System Many refuges allow hunting for specific species during defined periods, with the details for each unit in 50 CFR Part 32.20eCFR. 50 CFR Part 32 – Hunting and Fishing Expect restrictions you would not see on BLM land: limited entry areas, weapon type restrictions, designated hunting zones. Some refuges require a separate refuge-specific permit or entrance fee.
National Parks
National Park Service units are the most restrictive category. Hunting and trapping are prohibited by default unless Congress specifically authorized the activity in a park’s enabling legislation. Where Congress has authorized it, the superintendent still must determine it is consistent with public safety and sound resource management. Hunting is currently authorized in 76 NPS units, most of them designated as national preserves, recreation areas, seashores, or lakeshores rather than traditional national parks.21National Park Service. Hunting, Fishing, Trapping Activities Across the National Park Service Confirm the specific unit’s authorization before you go.
How Federal and State Rules Fit Together
For resident game species like deer, elk, and turkey, your state wildlife agency has full control. States issue licenses, set seasons, establish bag limits, and enforce their own regulations. Federal law enters through the specific statutes above.
In the field, the rule is simple: follow whichever law is more restrictive. If the federal bag limit for a migratory species is six birds and your state set it at four, your limit is four. If a species has no state-level protection but is listed as endangered, the federal take prohibition still applies. On federal land, the managing agency’s rules add another layer on top of both state and federal wildlife regulations. You are responsible for knowing all applicable rules, and “I didn’t know” is not a defense for most federal violations.
