The first flock can slip along a creek bend before the sun touches the cottonwoods. Wings flash, the dog stiffens, and a cold breath rolls off the water. Colorado duck hunting can feel like a secret tucked between corn stubble, prairie reservoirs, and high country ponds. Yet the law is never far away. It rides in your blind bag, in your shotgun plug, in your license, and in the clock on your phone.
Colorado duck hunting laws are set through both Colorado Parks and Wildlife rules and federal migratory bird rules. Ducks cross state lines like wind over grass, so hunters must follow more than one rulebook. A legal hunt starts with the right license, HIP number, duck stamps, legal shotgun, nontoxic shot, open season, daily limit, possession limit, and access rule for the land or water being hunted.

Colorado Is Split by Flyway
One of the first rules to learn is that Colorado is not treated as one single duck zone. The Continental Divide matters. East of the Divide falls in the Central Flyway. West of the Divide falls in the Pacific Flyway. That line changes season dates, daily limits, and coot limits.
The Central Flyway side has the Northeast Zone, Southeast Zone, and Mountain/Foothills Zone. The Pacific Flyway side has the Western Zone and Eastern Zone. If you hunt near the Front Range, the South Platte, the Arkansas River, the San Luis Valley, North Park, the Gunnison country, or the Western Slope, check the zone map before you trust a date. A wrong zone choice can make an open day look closed, or worse, make a closed day look open.
Who Needs a Colorado Hunting License?
To hunt ducks in Colorado, you need a small game hunting license or another license type that covers small game and migratory birds. Common choices include an annual small game license, a youth small game license, a small game and fishing combo license for qualifying residents, or a one-day small game license when it fits the hunt.
Colorado licenses and state stamps for small game and waterfowl run from March 1 through March 31 of the next year. That 13-month window can be handy, but do not let it blur the difference between license validity and season dates. A license may still be valid on paper while duck season is closed.
Most hunters also need proof of hunter education. Colorado generally requires hunter education for anyone born after January 1, 1949, before that person can buy or hold a hunting license. Hunters buying a license must also provide proper identification, proof of residency when claiming resident status, and a Social Security number or Individual Taxpayer Identification Number if age 12 or older.
Habitat Stamp, State Waterfowl Stamp, Federal Duck Stamp, and HIP
A Colorado Habitat Stamp is added to many license purchases for people ages 18 through 64. Some exemptions apply, but most adult hunters should expect to see it tied to the license transaction.
Waterfowl hunters age 16 or older need a Colorado State Waterfowl Stamp. The state stamp is printed on the hunting license and must be validated by signing the license in ink. Hunters age 16 or older also need a Federal Migratory Bird Hunting and Conservation Stamp, often called the Federal Duck Stamp. A physical federal stamp must be signed across the face. Under current federal rules, an electronic federal duck stamp can cover the full season from purchase through the following June 30.
Colorado also requires Harvest Information Program registration, usually called HIP, before hunting migratory birds. HIP is free, but it is not optional. Hunters can register through CPWShop, a CPW office, or a license agent. Keep the HIP number with your license. In the field, missing paperwork can feel heavier than a wet bag of decoys.
2025-2026 Colorado Duck Season Dates
As of late May 2026, Colorado Parks and Wildlife has said the 2026 brochure with updated season dates and fees will be available in August. The table below reflects the 2025-2026 Colorado small game and waterfowl season dates. Hunters planning a fall 2026 hunt should check the new booklet before making final plans.
| Flyway and Zone | Duck, Coot, and Merganser Season | General Daily Limit |
|---|---|---|
| Central Flyway, Northeast Zone | Oct. 18-Nov. 30, 2025 and Dec. 11, 2025-Jan. 31, 2026 | 6 ducks and mergansers in the aggregate |
| Central Flyway, Southeast Zone | Oct. 28, 2025-Jan. 31, 2026 | 6 ducks and mergansers in the aggregate |
| Central Flyway, Mountain/Foothills Zone | Oct. 4-Nov. 30, 2025 and Dec. 25, 2025-Jan. 31, 2026 | 6 ducks and mergansers in the aggregate |
| Pacific Flyway, Western Zone | Oct. 4-Oct. 21, 2025 and Nov. 6, 2025-Jan. 31, 2026 | 7 ducks and mergansers in the aggregate |
| Pacific Flyway, Eastern Zone | Oct. 4, 2025-Jan. 16, 2026 | 7 ducks and mergansers in the aggregate |
The September teal season for 2025 ran Sept. 13-21. The teal limit was 6 per day and 18 in possession. Early teal hunts can be fast and warm, but the same paperwork habits still matter. Know the species before the shot, because not every small duck in September is a legal teal.
Central Flyway Duck Limits
On Colorado’s Central Flyway side, the daily duck and merganser limit is 6 in the aggregate. That daily bag may include no more than 5 mallards, and only 2 of those mallards may be females. It may also include no more than 3 pintails, 2 canvasbacks, 2 redheads, 1 scaup, and 3 wood ducks.
The possession limit is 3 times the daily bag. For ducks and mergansers on the Central Flyway side, that means 18 total in possession. The coot limit on this side is 15 per day and 45 in possession.
Pacific Flyway Duck Limits
On Colorado’s Pacific Flyway side, the daily duck and merganser limit is 7 in the aggregate. Of that daily bag, no more than 2 may be female mallards. It may also include no more than 3 pintails, 2 canvasbacks, 2 redheads, and 2 scaup.
The possession limit is 3 times the daily bag. For Pacific Flyway ducks and mergansers, that means 21 total in possession. The coot limit on this side is 25 per day and 75 in possession.
Goose Rules That Duck Hunters Should Know
Many Colorado duck hunters also see geese during the same outing. Goose seasons do not always match duck seasons, and the rules vary by flyway and special area. Dark geese, light geese, and the Light Goose Conservation Order have separate dates and limits. During the Light Goose Conservation Order, recorded or electronically amplified calls may be used, unplugged shotguns are allowed, shooting hours run one-half hour before sunrise to one-half hour after sunset, and a federal duck stamp is not required. A Colorado waterfowl stamp is still required.
Those exceptions apply only to that special light goose season. Do not carry them back into a normal duck hunt. A rule that fits snow geese in spring can be dead wrong for mallards in January.
Shooting Hours
Colorado’s regular legal hunting hours for small game and waterfowl are one-half hour before sunrise to sunset. The Light Goose Conservation Order has a later end time, but regular duck hunting stops at sunset. Sunrise and sunset should be based on the place you are hunting, not the city where you bought shells.
Set your watch before the hunt starts. Morning fog, clouds, canyon shade, and snow glare can trick the eye. The clock is the cleanest answer. A flock at two minutes before legal time is still a flock to watch, not a flock to shoot.
Legal Shotguns, Plugs, and Nontoxic Shot
For migratory birds, shotguns may not be larger than 10-gauge. They must be fired from the shoulder. They also may not hold more than three shells in the chamber and magazine combined. If your shotgun can hold more, it must be plugged with a one-piece filler that cannot be removed unless the gun is taken apart.
Slugs are not legal for waterfowl. Nontoxic shot is required for duck, goose, merganser, and coot hunting. Steel, bismuth, and approved tungsten loads are common choices. Lead shot should not be in your blind bag during a duck hunt. One forgotten shell can spoil a morning faster than a dog shaking mud into your coffee.
Boats, Blinds, Decoys, Dogs, and Calls
Colorado allows waterfowl hunting from the open, from a blind, or from another concealed place, as long as it is not a sink box. Artificial decoys are allowed. Dogs may be used to flush, point, retrieve, pursue, or bring birds to bay. Hand calls are legal for ducks and geese.
Recorded or electronically amplified bird calls are not legal for regular duck hunting. They are allowed for crows and during the Light Goose Conservation Order, but not for normal ducks. That is one of the easiest rules to mix up, so keep electronic callers out of the duck blind unless you are in a season where the rule allows them.
Motorized boats have their own limits. Hunters may hunt from a vessel with a motor or sail only after the motor is off, the sail is furled, and forward motion from that power has stopped. Drifting boats and hand-powered boats are allowed. Motorized boats may be used to pick up dead or injured birds and to set or retrieve decoys.
Baiting and Crop Rules
Baiting is illegal for ducks. A baited area is any place where salt, grain, feed, or another lure has been placed, exposed, scattered, or distributed in a way that could attract migratory birds. The area remains baited for 10 days after all bait is removed.
Hunting over standing crops, flooded standing crops, flooded harvested crop fields, standing flooded natural vegetation, and areas affected by normal agricultural work can be legal when the field is not otherwise baited. The line between a lawful crop field and a baited spot can be thin, like ice on a backwater. When a field looks too perfect because grain was dumped or spread for birds, leave it alone.
Roads, Vehicles, Aircraft, and Drones
Colorado bans killing, capturing, injuring, or harassing wildlife from a motor vehicle or aircraft. It is also illegal to discharge a firearm from, on, or across a public road. For rifles, handguns, shotguns firing a single slug, and archery gear, Colorado has a 50-foot rule on each side of the center line of a public road. For duck hunters, the safer habit is simple: get well away from roads and shoot only where your shot path is safe and lawful.
Drones may not be used to look for, scout, or detect wildlife as an aid in hunting. A drone over a pond can feel like a shortcut, but the law treats it as an unlawful aid. Scouting still belongs to boots, binoculars, maps, and time.
Retrieval, Meat, and Possession
Colorado requires hunters to take edible portions of small-game birds from the field and prepare them for human food. A hunter should also make a real effort to track and kill wounded wildlife. A crippled duck is not a loose end to ignore. It counts against the hunt in both law and conscience.
Possession matters after the shot. The daily bag is what you may take in one day. The possession limit is the total number you may have after more than one day of lawful hunting. Birds in your truck, cooler, camp, freezer, and with a processor can all count. Keep species and sex limits in mind when birds are cleaned or shared.
Transport and Identification
Federal migratory bird rules require species identification during transport. As a field habit, keep the head or one fully feathered wing attached until the bird reaches your home or a migratory bird preservation facility. This helps prove whether the bird is a mallard hen, pintail, scaup, canvasback, redhead, or another species with a tight cap.
If birds are left with another person, shipped, gifted, or taken to a processor, tag them with the hunter’s name, address, signature, date taken, species, and number of birds. A clean tag is cheap insurance. It tells the story of the birds when you are not standing beside them.
State Wildlife Areas and Reservations
Some Colorado properties require reservations to hunt waterfowl. Reservation time slots generally open at 9:00 a.m. Mountain Time and can be made up to 14 days before the hunt date. State wildlife areas, state trust lands, national wildlife refuges, and walk-in access properties can each carry their own entry times, parking rules, boating rules, closed zones, dog limits, and blind rules.
Do not assume public land means open access every day. A locked gate, posted closure, check station rule, or reservation rule can control the hunt. The property rule is the last gate before the blind.
Pre-Hunt Colorado Duck Law Check
Before a Colorado duck hunt, confirm the flyway, zone, season date, split dates, shooting hours, daily duck limit, species caps, coot limit, possession limit, license, Habitat Stamp, HIP number, state waterfowl stamp, Federal Duck Stamp, shotgun plug, nontoxic shells, land access rule, and any reservation duty. Then check your vest and blind bag for lead shells or an electronic caller that does not belong on a duck hunt.
Colorado duck hunting laws can look dense at first, but they settle down when broken into field steps. Hunt the right zone on the right date. Carry the right papers. Use the right shot. Stop at sunset. Stay within the bag. Keep birds tagged and identifiable. Respect private land, refuge signs, and state property rules. Do that, and the law becomes part of the hunt’s rhythm, like decoys bobbing in a north wind and mallards trading over a frozen bend.
