Hunting for Lesser Scaup: Coastal vs. Inland Techniques

Understanding Lesser Scaup Behavior

What Makes Scaup Unique

• True divers: They feed by diving for invertebrates, mollusks, aquatic vegetation, and freshwater mussels.

• Travel in large rafts: Late-season birds gather in huge numbers on big water.

• Respond strongly to motion & visibility: More visual than puddle ducks.

• Use wind and wave lines: They often raft on windward shorelines and fly low over open water.

Scaup are highly migratory and can show up overnight during strong cold pushes—scouting pays off.

Coastal Techniques for Hunting Lesser Scaup

Coastal bays, sounds, and estuaries offer excellent scaup hunting during migration and wintering periods.

Where to Find Scaup on the Coast

• Open bays near mussel beds

• Ledges and drop-offs adjacent to flats

• Tidal edges with consistent current

• Windward shorelines where food concentrates

Focus on areas with both feed (shellfish, small crustaceans) and raft zones protected from heavy swell.

Coastal Decoy Spreads

Scaup on the coast expect big visibility:

• 4–10 dozen diver decoys: bluebills, cans, redheads, and buffleheads mixed in

• Add longlines to keep spreads organized in wind and tide

• Use motion decoys (pulsators, wigglers) in calm water

• Keep a landing “runway” pointed downwind for low incoming flights

Boat Blinds & Shore Setups

• Layout boats excel on coastal flats

• Big-water blind boats should be well-brushed and low-profile

• Shore hunters should focus on windward points, sandbars, or marsh islands

• Avoid deep water drop-offs where recovery becomes difficult

Shot Strategy on the Coast

• Expect fast, low passes

• Use modified or improved modified choke

• #2 or #3 steel for clean kills on tough divers

• Lead generously—bluebills fly deceptively fast over open water

Inland Techniques for Hunting Lesser Scaup

Lakes, reservoirs, and large rivers hold scaup throughout migration, but the birds behave differently than coastal flocks.

Finding Inland Scaup

Look for:

• Points, peninsulas, and wind-blown shorelines

• Creek channels and submerged humps

• Sheltered coves during storms

• Mussel beds or patches of submerged vegetation

Cold fronts push scaup south across interior flyways—watch lakes for new flocks after a northerly blow.

Inland Decoy Spreads

You don’t need ocean-sized numbers:

• 2–6 dozen diver decoys are enough on most reservoirs

• Run J-hooks or V-spreads to funnel birds downwind

• Mix in a small line of puddle duck decoys to add confidence

• Use high-contrast drake decoys for long-range visibility

Blinds & Positioning

• Shore blinds on points or gravel bars are ideal

• Bridge pilings and causeways provide natural funneling

• Rivers require upstream-facing spreads where current carries motion naturally

Shot Opportunities Inland

• Birds often commit tighter than on the coast

• Shots range from 15–35 yards

• IC or modified chokes work well

• Stay hidden—divers flare quickly when approaching land-based blinds

Key Differences: Coastal vs. Inland Scaup Tactics

Gear Tips for Lesser Scaup Hunts

• Waders with good traction for rocky shorelines

• White or gray layout blinds on open water

• Heavy anchors for longlines in wind

• Dog stand or platform for rough-water retrieves

• PFDs and cold-weather safety gear for big-water hunts

Visibility, stability, and safety matter on any diver hunt.

Weather & Migration Timing

• Cold fronts: Bring fresh birds to both coast and interior

• Strong winds: Concentrate scaup on wind-struck shorelines

• Bluebird days: Birds raft offshore and move less

• Stormy weather: Push flocks into sheltered coves and behind points

Late-season scaup often raft in huge numbers—find them, and you’ll find fast gunning.

Common Mistakes to Avoid

• Too few decoys on the coast for wary divers

• Improper longline spacing leading to tangled spreads

• Setting up in slack wind—divers need defined landing paths

• Taking sky-high pass shots—wait for committed birds

• Underestimating waves and wind on large water

Solid fundamentals beat gimmicks every time.

FAQs About Hunting Lesser Scaup

Q: Can you mix species in a scaup spread?
Yes—redheads, cans, ringnecks, and buffleheads add realism and visibility.

Q: Do mojos or spinners help?
For divers, not much. Motion on the water matters more than spinning wings.

Q: What’s the best load for scaup?
#2–#3 steel or #4 bismuth for close-in river hunts.

Q: Are scaup good to eat?
Yes—properly breasted and cleaned scaup taste excellent, especially younger birds from inland waters.

Q: How far offshore should I hunt?
As far as safety allows. Birds raft on big water, but points and wind lines often bring them close enough to shore setups.

Final Thoughts

Whether you’re targeting lesser scaup along wind-lashed coastlines or inland reservoirs, the keys to success remain the same: visibility, motion, smart positioning, and reading how divers use wind and water. When you tailor your spread and setup to the landscape, bluebill hunts can be some of the most exciting days in the waterfowl season.
