Mourning dove birdhouse plans look different from most nest box designs because the bird itself is different. Mourning doves do not excavate cavities or use enclosed boxes. They nest on open platforms, usually in conifers, shrubs, or sheltered ledges. This guide gives you a simple, buildable platform design with a full cut list, the tools you need, assembly steps, and the mistakes to avoid so your build actually gets used.

What Mourning Doves Need in a Nesting Structure

Before you cut anything, it helps to understand what doves look for. They build loose, flimsy nests of twigs, so they need a flat, stable surface that will not wobble in wind. They also prefer a spot with overhead cover from rain and predators and a clear approach for landing. A platform that is too small or too exposed will often be ignored.

Plan on these basic requirements:

• A flat floor at least 10 inches by 10 inches, with 12 by 12 inches being a comfortable size.
• A low rim, about 1 inch high, to keep eggs from rolling off during incubation.
• Overhead shelter, either a roof or a nearby branch cover, to block rain and direct sun.
• Mounting at roughly 6 to 15 feet off the ground, on a post, bracket, or in a tree fork.
• Drainage holes in the floor so rainwater does not pool under the nest.

Materials and Tools You Will Need

This project uses dimensional lumber and basic hardware. Untreated cedar, pine, or fir works well, and exterior-grade plywood is a good choice for the floor. Avoid pressure-treated wood with strong odors, and never use painted or stained surfaces inside the nesting area.

• One 1×6 board, 6 feet long (for the sides and rim pieces)
• One piece of 1/2 inch exterior plywood, 12 by 12 inches (for the floor)
• Exterior wood glue and 1 1/4 inch exterior screws
• Galvanized or stainless steel screws for corrosion resistance
• A circular saw or miter saw, a drill with a 3/16 inch bit, and a tape measure
• Clamps, a square, and sandpaper (120 grit)

Cut List and Dimensions

All dimensions below are finished sizes. Cut carefully and dry-fit the parts before applying glue.

Step-by-Step Assembly

Step 1: Prepare the Floor

Cut the plywood floor to 12 by 12 inches and sand the edges smooth. Drill four drainage holes, each about 3/8 inch in diameter, near the corners of the floor. These holes keep water from sitting under the nesting material and reduce mold risk.

Step 2: Attach the Rim

Glue and screw the front and back rim pieces flush with the floor edges, then attach the two side rim pieces between them. Keep the rim at 1 inch high above the floor surface. The rim should sit on the top face of the floor, forming a shallow tray. Clamp each piece while the glue sets, and drive two screws into each joint.

Step 3: Build the Roof Supports

Cut the two angled support brackets. Attach one bracket to each side of the rim, positioned so the top of the bracket reaches the underside of the roof. Use glue and two screws per bracket. These supports keep the roof from sagging and give the structure rigidity.

Step 4: Attach the Roof

Center the 14 by 6 inch roof board over the platform so it overhangs about 1 inch at the front and back. Screw it into the top of the supports from below. The overhang sheds rain and keeps the nest dry during storms.

Step 5: Mount the Platform

Choose a mounting spot in a conifer or dense shrub, or attach the platform to a post or wall bracket. Position it so it faces away from prevailing winds and gets morning sun but some afternoon shade. Secure the base with exterior screws through the floor into a solid support. A stable, non-wobbling mount is essential, since doves will abandon a platform that shakes.

Step 6: Finish Lightly

Sand all exposed edges and corners to prevent splinters. Do not paint or stain the floor or rim where the nest will sit. If you want to protect the exterior, apply a single coat of clear, unpigmented sealer to the outside of the roof and sides only, and let it cure fully before mounting.

Placement and Seasonal Tips

Mourning doves nest from early spring through late summer, and some pairs raise several broods in one season. Install the platform in late winter so the birds have time to find it before nesting begins. Keep the area around the platform free of heavy brush that might attract cats, and position the structure away from feeders, since crowded feeding stations can attract predators and increase disease spread.

Once the platform is in place, avoid disturbing active nests. Look for a loose, shallow pile of twigs with one or two white eggs. If a nest is occupied, leave it alone until the young have fledged, which usually takes about two weeks after hatching.

Common Mistakes

• Making the platform too small. A floor under 10 inches square can feel unstable to nesting pairs.
• Omitting the rim. Without a rim, eggs and nesting material slide off during wind or rain.
• Skipping roof cover. Exposed platforms often fail after heavy rain or intense midday sun.
• Using painted or treated wood inside the nest area. Fumes and residues can harm eggs and nestlings.
• Mounting too low or too high. Positions under 6 feet or over 15 feet are less likely to attract nesters.
• Forgetting drainage. Standing water quickly ruins nesting material and promotes bacteria.

Tips for a Better Build

• Pre-drill all screw holes in the rim and roof to prevent splitting the cedar or pine.
• Round over the top edges of the rim with sandpaper so the surface feels smooth to landing birds.
• Build two platforms if you have space. Doves are often more willing to nest near an existing structure.
• Check the platform each spring for loose screws, rot, or wind damage before nesting season begins.

Recommended gear

A few tools make this build faster and cleaner, especially the pre-drilling and joint-clamping steps.

• Cordless drill with a bit set. A drill makes pilot holes and driving screws quick, and a 3/16 inch bit handles the drainage holes. View on Amazon
• Bar clamps. Clamps hold the rim and bracket joints square while the glue cures. View on Amazon
• Exterior wood glue. A waterproof glue rated for outdoor use keeps joints strong through rain and temperature swings. View on Amazon
• Stainless steel exterior screws. These resist rust and staining from weathered cedar and pine. View on Amazon

FAQ

Do mourning doves use regular birdhouses?

No. Mourning doves almost always nest on open platforms or in dense vegetation rather than enclosed boxes. A platform with a rim and overhead cover is the best option.

What size should a mourning dove platform be?

A floor of about 12 by 12 inches is a good target, with 10 inches square as the practical minimum. The 1-inch rim keeps eggs in place.

How high should I mount the platform?

Between 6 and 15 feet is typical. Placement in a conifer or shrub with overhead cover often works better than a fully exposed post.

Should I paint the platform?

Avoid painting or staining the nesting surface. If you want exterior protection, seal only the outside of the roof and sides with a clear, unpigmented finish and let it cure fully.

When do mourning doves start nesting?

Nesting typically begins in early spring and can continue into late summer, with several broods possible in one season depending on local conditions.

Do I need to clean the platform?

Remove old, wet nesting material once nesting season ends. Clean the platform with a brush and water, let it dry completely, and check the screws and rim for damage before the next season.

Will mourning doves reuse the same platform?

Often yes, especially if the platform is in a good location and the birds had a successful nesting experience there. Keeping the structure stable and dry improves the chances of reuse.

Conclusion

A well-built platform gives mourning doves a stable, sheltered place to raise their young. With a 12-inch floor, a low rim, overhead cover, and a secure mount, this simple project meets the birds’ basic needs. Build it with exterior-safe materials, mount it thoughtfully, and check it each spring to keep it ready for the nesting season.
