Hunting for Lesser Scaup in Open Water: A Complete Waterfowler’s Guide
Lesser scaup—often called “bluebills”—are among the most common diving ducks in North America, yet they remain one of the most challenging species to hunt consistently. Known for their fast flight, open-water habits, and large winter rafts, scaup demand a specific approach that differs from classic marsh puddle-duck hunting.
This guide breaks down everything you need to know—gear, decoys, scouting, boat setup, safety, and shooting techniques—to help you hunt scaup with confidence. If you’re planning a bigger waterfowl adventure or comparing guided duck hunts, platforms like Find A Hunt make it easy to review and book reputable outfitters.
Understanding Lesser Scaup Habitat & Behavior
Lesser scaup are true open-water divers. Their habits influence every part of your hunt—from scouting to concealment.
Where You’ll Find Them
-
Large lakes and reservoirs
-
Broad river systems
-
Open bays and coastal estuaries
-
Deep-water feeding areas rich in invertebrates and vegetation
Key Behavior Patterns
-
Travel in big rafts: Especially late season
-
Prefer deeper water: Often 10–30 feet or more
-
High-speed flyers: Fast, low, and often in tight flocks
-
Respond to big, bold decoy spreads: Especially when migrating
Knowing when and where scaup move helps you set up in zones where birds naturally trade between feeding and resting areas.
Essential Gear for Hunting Lesser Scaup
Shotguns & Loads
Scaup are hardy, fast-moving divers. Use:
-
12- or 20-gauge shotguns
-
Modified or improved modified chokes
-
Steel or bismuth shot: #2 to #4 is ideal
Waders & Clothing
For open-water setups:
-
Breathable or insulated waders
-
Waterproof outerwear
-
Wind-resistant layers—open water can get cold fast
Boats & Blinds
Most scaup hunts require:
-
A layout boat
-
A boat blind on a jon boat or duck boat
-
A stable platform for open-water decoy placement
Safety and stability are critical in big water.
Optics & Safety Gear
-
Binoculars for scouting
-
Life jackets or float coats
-
Navigation lights and anchor ropes
-
Dry bag for essentials
Decoy Strategies for Lesser Scaup
Scaup respond well to large, visible spreads. Because they raft up naturally, your decoy spread should mirror this behavior.
A Productive Spread Includes:
-
3–6 dozen diver decoys
-
A mix of drake-heavy scaup blocks for visibility
-
Additional divers like buffleheads, goldeneyes, or redheads for realism
-
Motion decoys (jerk rig or water agitator) to add ripple on calm days
Best Spread Shapes
-
“J” Hook: Long tail of decoys leading into a body—great for directing birds
-
Large blob/raft: Effective when birds are in big groups
-
“X” Pattern: Works well with layout boats, positioning shooters in the center
Placement Tips
-
Keep landing pockets 15–25 yards downwind of your blind setup
-
Use high-contrast drake decoys to improve long-range visibility
-
Keep your blind or layout boat tight to the spread without skylining yourself
Calling Techniques for Scaup
While scaup aren’t as call-responsive as puddle ducks, calling still matters.
When to Call
-
During migration setbacks or poor visibility
-
When small flocks express interest but won’t commit
-
To “finish” birds into the landing zone
Effective Calls
-
Higher-pitched hail calls used sparingly
-
Fast, sharp quacks to mimic divers on the water
-
Soft chatter when birds are close
Less is more—scaup react mainly to visual cues, not heavy calling.
Scouting for Lesser Scaup
Scouting is crucial for diver duck success.
What to Look For
-
Large rafts sitting in feeding areas
-
Flight lines between bays, lakes, or river systems
-
Points, islands, or submerged structure that attract resting flocks
-
Fresh droppings and feathers on shorelines
Best Times to Scout
-
Midday when scaup raft up in predictable spots
-
Early morning to watch their travel corridors
-
Calm weather days—easier to glass large water bodies
Shooting Tips for Fast-Flying Scaup
Scaup are fast, agile divers. Clean shooting is essential.
Key Shooting Techniques
-
Lead aggressively: More than you think
-
Shoot into the front of the flock, not the middle
-
Pick out a single bird and stay locked on it
-
Maintain strong footing in boat blinds—waves can impact aim
Because scaup fly tight and fast, discipline makes the difference between doubles and clean misses.
Weather & Conditions That Impact Success
-
Wind: A steady breeze pushes birds low and predictable
-
Cloudy days: Birds decoy more readily
-
High-pressure bluebird days: Expect higher flights and less commitment
-
Cold snaps: Concentrate scaup on open pockets when shorelines freeze
Use weather patterns to pinpoint productive days.
Safety Considerations for Open Water
Hunting scaup requires strict safety awareness:
-
Always wear a life jacket or float coat
-
Anchor your boat securely
-
Avoid overloading layout boats
-
Respect wind forecasts—big water can turn dangerous fast
-
Keep communication devices dry and accessible
Put safety first—big water demands experience and caution.
FAQs: Hunting Lesser Scaup
How do you tell lesser scaup from greater scaup?
Lesser scaup have a peaked head shape; greater scaup have rounder heads and wider bills. In flight, identification is often difficult.
When is the best time to target scaup?
Mid to late season, when large flocks migrate south, offers the most consistent hunting.
Do scaup decoy well?
Yes—especially to large spreads with lots of visibility.
Is calling necessary?
Not always. Visual cues—decoys and motion—matter most.
Do scaup taste good?
Divers have stronger flavor than puddle ducks. Proper field care and cooking methods (slow cooking, marinades) improve flavor significantly.
