Board cut schedule
Every panel you'll need to cut, sized to actual milled lumber dimensions. Print this page or download the PDF to take into your workshop.
| Panel | Dimensions | Qty | Notes |
|---|---|---|---|
| Back | 11.25″ × 32″ | 1 | Provides 4" mounting flanges at both top and bottom |
| Front | 11.25″ × 24″ | 1 | Cut 3"x4" oval hole 4" from top; staple hardware cloth 'ladder' to the inside face below the hole |
| Side (Fixed) | 11.25″ × 24″ | 1 | Slope top edge from 24" back to 20" front to match roof pitch |
| Side (Door) | 11.25″ × 24″ | 1 | Hinge from the top for cleaning; trim 1/4" off bottom for clearance |
| Roof | 11.25″ × 16″ | 1 | Provides a 3" overhang in the front to protect from rain |
| Floor | 9.75″ × 11.25″ | 1 | Recess 1/2" up from bottom; drill four 1/2" drainage holes |
Source board layout
The floor is cut to 9.75" to fit between the two side panels. The front and back panels overlap the side edges. A 12-foot board allows for the extra height required for Wood Duck cavities and the necessary mounting extensions.

Construction notes
- Wood: 3/4-inch (19 mm) untreated cedar, cypress, or redwood. Never use pressure-treated lumber.
- Boards: A single 1" x 12" x 12' untreated cedar board provides all necessary panels including the oversized roof and mounting backboard.
- Hardware: 35x 2" stainless steel or galvanized deck screws, 2x 2" exterior brass hinges, 1x stainless steel gate latch, 18" x 10" piece of 1/4" galvanized hardware cloth, Staples for hardware cloth, 4 inches of kiln-dried cedar shavings
- Ventilation: Leave a 1/2-inch gap between the top of the side panels and the roof, or drill three 1/2-inch holes near the top of each side panel.
- Drainage: Drill four to six 1/2-inch holes in the floor panel and clip 1/2-inch off each corner to ensure the nesting material stays dry.
- Predator guard: A 36-inch wide cone-shaped metal baffle or a 4-foot long stovepipe guard is mandatory. The oval entrance hole (4" wide by 3" tall) is specifically designed to prevent larger raccoons from entering.
Install it
Place it & time it right
Install over water or within 100 feet of a permanent wetland or pond. Ensure there are no overhanging branches within 5 feet that would allow raccoons to drop onto the roof. Space boxes at least 50-100 feet apart to reduce 'dump nesting' by multiple females.
Seasonal timeline
When to install
Late January in the South; early to mid-March in Northern states and Canada
Nesting begins
In the Southeast, nesting begins as early as February. In the Midwest and Northeast, peak activity is April through May. Western populations typically begin in late March.
Eggs & incubation
6-16 eggs (can be higher if 'dump nesting' occurs) · 28-32 days
Fledging & cleaning
24 hours after hatching (ducklings jump from the box) · Clean the box every January. Remove old nesting material and add 4-6 inches of fresh cedar or pine shavings, as Wood Ducks do not carry their own nesting material.
Regional considerations
Wood Ducks breed across most of the central and eastern United States, the Pacific Coast, and southern Canada. They require wooded wetlands, swamps, or riparian corridors with quiet water and plenty of cover.
Nesting follows the spring thaw. Birds in the Deep South may start 8-10 weeks earlier than those in the Great Lakes region. High-elevation mountain populations may delay nesting until late May.
Raccoons and starlings are the primary threats. A metal cone baffle prevents climbing, while the specific 3x4 inch oval entrance hole denies entry to larger raccoons and discourages starlings.
Add a camera
Watch it happen
Because Wood Duck boxes are significantly deeper than standard songbird houses, internal camera placement is best achieved by mounting a wide-angle, IR-equipped camera in one of the top rear corners. This allows for a full view of the hen and the clutch while keeping the hardware out of the path of the ducklings' upward scramble. Ensure all cables are secured with staples and exit through a small hole at the top to prevent entanglement.
External cameras are equally valuable for Wood Ducks, particularly for capturing the spectacular moment when the ducklings fledge. Position a weather-proof outdoor camera on a nearby post or tree, approximately 6 to 10 feet away, aimed directly at the entrance hole. High frame-rate settings are recommended to capture the fast-moving 'jump' which usually occurs early in the morning, approximately 24 hours after hatching.
Since Wood Ducks are sensitive to light and human activity near the nest, avoid using cameras with visible white LEDs for night vision; instead, rely strictly on 940nm 'no-glow' infrared. Routing power is the biggest challenge for these wetland-based boxes, so consider a solar-powered camera kit or a long-range wireless bridge if the box is positioned far from the house.
For interior monitoring, a small USB-powered interior cam with a wide lens is ideal. For the exterior perimeter, a high-quality trail camera with a fast trigger speed can monitor for predators like raccoons or competing starlings, providing essential data on the success of your habitat placement.
Off-grid power with a USB solar panel
Nest boxes are almost always far from a power outlet. A 5V USB solar panel with a built-in battery is the cleanest solution — it powers most interior USB cameras, Blink cameras (via their USB port), and many trail cameras indefinitely.
- Panel position: Mount on the same post as the box, 1–2 ft above, angled 30–45° from vertical and facing south.
- Cable routing: Run inside split loom or 1/2″ conduit so squirrels can't chew it. Enter through the same grommeted hole as the camera cable.
- Battery buffer: Pick a panel with a 5–10 Ah battery so the camera runs through cloudy days and overnight for nocturnal species.
- Weatherproofing: Wrap every cable connection in self-amalgamating rubber tape.
Troubleshoot
Common problems & solutions
Dump nesting (too many eggs)
Space boxes further apart (100+ feet) and out of direct visual line-of-sight from one another.
European Starling occupation
Clean out starling nests immediately and ensure the oval hole is exactly 3 inches high to make entry difficult.
Ducklings cannot climb out
Always install a 1/4" hardware cloth ladder or deeply roughen the inside front panel so day-old ducklings can reach the hole.
Bees or wasps
Rub the interior ceiling with a bar of unscented soap to prevent combs from adhering.
Raccoons reaching in
Ensure the distance from the hole to the eggs is at least 15 inches and use the recommended oval hole shape.
Common questions
Frequently asked questions
A Wood Duck box requires an oval entrance hole exactly 3 inches high and 4 inches wide. This specific shape allows the duck to enter while preventing larger predators like raccoons from fitting through.
Mount the box 6 to 30 feet high. If mounting over land, stay closer to 10-15 feet to deter predators; if over water, 6-8 feet is sufficient if the water level is stable.
Boxes should be in place by late winter (January or February) to ensure they are ready for the first arrival of hens looking for nesting sites.
The box should face open water or a clear flight path (South or East is usually best). Avoid facing it into dense brush where predators can hide and flight is obstructed.
Use the 3x4 inch oval hole and monitor the box weekly. Starlings dislike deep, dark boxes, but if they persist, remove their nesting material immediately before they lay eggs.
Yes, unlike many birds, Wood Ducks do not carry material into the box. You must provide 4-6 inches of fresh wood shavings (not sawdust) at the start of every season.
Clean the box once a year in mid-winter (January). Remove all old debris and replace the wood shavings to ensure a parasite-free environment for the next brood.
