How to Make Birdhouses with Recycled Wood

Learn how to make birdhouses by using recycled wood and screws. Choose what birdhouse hole size is best to attract beneficial birds to your property.

What’s more exciting than the appearance of a nesting pair to set up housekeeping in a new birdhouse? Once you’ve had the pleasure of creating one successful domicile, you’ll want to develop a whole neighborhood. It’s especially satisfying to help establish a population of beneficial birds, such as swallows, that return the good deed by keeping your yard mosquito free. These simple birdhouses–made from a piece of recycled wood, a few nails, and an old license plate–require no special carpentry skills and can be assembled in less than two hours.

How to Make Bird Houses

Cut wood into 2 pieces, both about 10 inches long. These will be the front and back of the birdhouse. Cut 3 pieces, each about 4 inches long, for the sides and the bottom.

Before you cut the arc in the front and back that will be the roofline, determine how high the sides will be. Measure the long side of one of the side pieces and add the thickness of the bottom board. Mark this distance up from the bottom on each edge of the front piece. Using a compass or even the edge of a dinner plate, draw an arch that curves between these two marks. Repeat on the back piece. For the curved roof, cut the curve on the front and back of the house with a jigsaw. For a peaked roof, use a hand saw to make the angled cuts of the roofline.

Use a forstner or paddle bit in the appropriate size to drill the entry hole in the center of the front board.

Use screws with large heads or galvanized nails (do not use finish nails) to attach the pieces. Old wood is prone to cracks, so it’s important to pre-drill the holes. Start by attaching the bottom to the 2 sides as shown above.

Attach the top and back to the U-shaped sides and bottom using 2 screws or nails on each side and 2 at the bottom.

For the curved roof, gently bend the license plateinto an arc, then attach it with a nail or screw (pre-drilled again) at the top of the house’s curve. Add 2 more nails at intervals down the sloping sides, along both the front and back edge, for a total of 10 nails. For the peaked roof, bend the license over the edge of a table to make a crisp crease. To finish the roof, crimp the edges of the license plate to make a jaunty edge. If needed, drill small holes in the bottom and the sides of the birdhouse for drainage and ventilation.

Birdhouse Hole Size by Species

There’s a lot of conflicting advice about birdhouse features needed to attract specific species, but experts agree that birds often surprise you by taking up residence in a house built to the specifications of an entirely different species. These recycled birdhouses let you experiment with little cost to you or the environment.

Hole diameter is one of the main features that makes a birdhouse right for one species and not so ideal for another. The U.S. Fish and Wildlife Service Office of Migratory Bird Management website has tips on attracting specific bird species and siting birdhouses.

Sample hole dimensions for a few bird species

Swallows (Violet-green and Tree): 1-1/2 inches diameter
Bluebirds (Eastern, Western and Mountain): 1-1/2 inches diameter
Flycatchers: 1-1/2 to 1-3/4 inches diameter
Nuthatches: 1-1/4 to 1-3/8 inches diameter
Chickadees: 1-1/8 inches diameter
