Building a birdhouse is a fun and rewarding DIY woodworking project. A handmade birdhouse makes a great addition to any backyard or garden, providing nesting spots and shelter for local bird species. With some basic carpentry skills and tools, you can easily build a custom birdhouse adapted to your specific needs and style. This comprehensive guide covers everything you need to know to build your own birdhouse from scratch.
Selecting the Right Birdhouse Design and Size
The first step in building a birdhouse is choosing an appropriate design and size for your target bird species. Consider the following factors:
Bird Species
- What birds do you want to attract? Identify some common backyard birds in your area and research their preferred nesting box dimensions. For example:
- Chickadees: 4 x 4 x 6 inches
- Bluebirds: 5 x 5 x 9 inches
- Wrens: 4 x 4 x 6 inches
- Build the birdhouse to the correct dimensions for your desired species. The entry hole size is also important and should be tailored to allow the target species to enter, while excluding larger species.
Nesting Needs
- Leave adequate interior space for the birds to build their nests.
- For example, chickadees need a 4 x 4 inch floorspace.
- Include features like drainage holes, ventilation gaps, grooved interior sides for climbing, and a rough interior surface for grip.
- Use untreated, unpainted wood. Avoid pressure-treated lumber, which contains chemicals toxic to birds.
- Include a removable side or roof panel to allow for annual nest cleaning/maintenance.
Placement
- Where will the birdhouse be installed? Tailor design features accordingly:
- Protection from predators, weather, and Mimimize competition
- Easy to clean and monitor
- Visible enough for you to observe nesting behaviors
House Style
- Customize with decorative elements like painted exteriors, engraved signs, shingled roofs, etc. Just keep functional elements in mind.
Gathering the Right Tools and Materials
Building a birdhouse requires just a basic toolkit and a few key materials:
Tools
- Handsaw or miter saw – to cut wood boards to size
- Drill and drill bits – to create entry hole and ventilation gaps
- Hammer and nails – to assemble the boards
- Sandpaper – to smooth edges and create grip
- Paintbrushes – if painting/staining exterior
Materials
- Untreated wood boards – cedar and pine are weather-resistant options
- Wood glue
- Roofing materials – shingles, metal sheeting, etc.
- Hinges and hook – for removable cleaning side/roof
- Wood putty – to seal cracks
- Exterior paint, stain, or wood finish – for decorated houses
Plywood, scrap wood, and dimensional lumber from the hardware store all work well. Just be sure it’s not pressure treated.
Cutting Pieces to Size
Once you’ve chosen a birdhouse design and gathered supplies, it’s time to start cutting. Follow these steps:
- Refer to schematics and measure exterior dimensions of the birdhouse. Account for wood thickness in calculations.
- Cut boards to the appropriate lengths and widths for each component – the front, back, sides, roof, floor, etc.
- Use your saw to cut entrance hole in the front piece. The diameter varies by species, usually 1-1 1/2″.
- Drill ventilation holes in the sides or roof. These provide airflow.
- Cut out clean openings for removable panels, like a side cleaning access.
- Sand all cut edges smooth so there are no splinters.
Take exact measurements and cut all pieces carefully for a professional end result. Avoid forcing pieces together that don’t fit.
Assembling the Birdhouse
Once the pieces are cut, it’s time for assembly. Follow these tips:
Use Waterproof Glue
Apply exterior-grade wood glue between all joining surfaces to waterproof the birdhouse. This prevents rain from seeping in.
Nail and Screw Strategically
Use a hammer, nails, and exterior screws to assemble the pieces. Nail/screw from multiple angles for extra stability. Don’t skimp on hardware – sturdy construction is key.
Attach Removable Panels
Screw hinges onto any removable cleaning panels to allow them to swing open. Install a hook closure.
Fill Gaps
Seal any cracks and holes with wood putty to prevent drafts and keep interior dry.
Add Perch
An exterior perch below the entry hole gives birds a place to land before entering. Attach a small trimmed piece of wood with glue and nails.
Include Drainage
Drill a few holes in the birdhouse floor to allow rainwater to drain out.
Applying Exterior Finish
For a fully polished birdhouse, add decorative exterior touches:
Sand Surface
Lightly sand to smooth any rough patches for better paint adhesion.
Prime and Paint
Apply 1-2 coats of exterior primer then use acrylic paint for the finish coat.
Stain or Clear Coat
Alternatively, brush on a tinted wood stain or use a clear coat for a natural look.
Add Design Details
Get creative with patterns, engraved names/signs, decorative roof shingles, etc.
Seal With Polyurethane
Finish with 2-3 coats of exterior polyurethane sealer to protect the wood from weathering.
Installing the Completed Birdhouse
Once construction is complete, it’s time for installation. Here are some tips:
Choose Location
Pick a sheltered spot away from prevailing winds and rain. Near trees or shrubs works well.
Mount Securely
Attach birdhouse firmly to a fence post, tree trunk, or pole using brackets or a predator guard to deter snakes/raccoons.
Adjust Height
Mount most boxes 5-10 feet high. Sparrows prefer lower heights though.
Position and Angle
Face entrance hole away from wind/rain. Tilting slightly down allows rain drainage.
Space Properly
Separate multiple houses 10-30 feet apart to minimize competition and territory issues between birds.
With the right construction and placement, your custom birdhouse will soon host happy feathered friends!
FAQs About Building Birdhouses
What kind of wood is best for building a birdhouse?
Cedar and pine are great wood choices because they are naturally weather-resistant. Avoid pressure treated wood since it contains toxic chemicals. Upcycled scrap wood or dimensional lumber from the hardware store also works well.
What tools do I need to build a birdhouse?
You’ll need basic woodworking tools like a saw, drill, hammer, nails, sandpaper, glue, and paintbrushes if decorating. No need for fancy power tools. A handsaw, miter saw, or jigsaw can cut the wood.
What is the ideal birdhouse size?
It depends on the target bird species. Do research to find recommended interior floor dimensions. For example, chickadees need a 4 x 4 in floorspace. Leave 5-6 in of headspace above the floor too. The entry hole is also sized for certain species.
How deep should a birdhouse be?
Most small birdhouses range from 6 – 10 inches deep from front to back. This leaves enough room for nest building and fledglings. Add a few inches if targeting larger bird species. Just don’t make it too cavernous.
Should birdhouses have a perch?
Adding a small exterior perch below the entry hole will give birds a landing spot before entering. This is an optional decorative feature though not required.
Do birdhouses need ventilation?
Yes, include ventilation gaps in the roof or sides so airflow can circulate through the box. You want the interior to remain dry to prevent mold.
How high should I mount my birdhouse?
For most species, mounting your handmade birdhouse 5-10 feet above ground is ideal. Place it out of reach of predators. Adjust height based on the specific birds being attracted.
How far apart should multiple birdhouses be spaced?
When putting up several birdhouses, space them 10-30 feet from each other depending on species. This prevents territorial disputes between competing birds.
