Building a Bluebird House

Welcoming bluebirds to your yard can be a rewarding experience for homeowners across North America. These charming avian visitors bring vibrant colors and cheerful melodies to your outdoor space. Building a suitable birdhouse for bluebirds is an excellent way to encourage their presence and foster a thriving environment for these beautiful creatures.

Kinds of Bluebirds In North America

In North America, there are three primary species of bluebirds: the Eastern Bluebird, Western Bluebird, and Mountain Bluebird. Each species boasts unique characteristics, but all share a preference for open spaces, meadows, and fields. Offering them a comfortable dwelling ensures a better chance of attracting them to your yard.

What Type of Birdhouse Is Suitable

While the basic design of a bluebird house remains consistent, there are slight differences to consider for each species. Eastern Bluebirds prefer houses with a circular entrance hole of 1.5 inches in diameter, while Western Bluebirds and Mountain Bluebirds usually favor slightly larger holes of around 1.56 inches.

Dimensions of a Bluebird House

To accommodate bluebirds’ specific needs, a suitable bluebird house should have the following dimensions:

  • Overall House Dimensions: Approximately 5 inches wide, 5 inches deep, and 9-10 inches tall.
  • Entrance Hole Placement: Around 5-6 inches above the floor.
  • Floor Dimensions: Roughly 4×4 inches.
  • Entrance Hole Diameter: 1.5 inches for Eastern Bluebirds, 1.56 inches for Western and Mountain Bluebirds.

Materials Needed To Build A Bluebird House

Gathering the right materials is a crucial step in crafting a comfortable and durable bluebird house. You’ll need:

  • Untreated Wood: Cedar or pine are great choices due to their weather-resistant properties.
  • Screws: Rust-proof screws to secure the house together.
  • Saw, Hammer, and Screwdriver.
  • Drill (to make the entrance hole)
  • Measuring Tape: To ensure accurate dimensions.
  • Sandpaper: To smooth any rough edges.

How To Build Your Bluebird House

Here are the simple steps you need to build your own bluebird house!

Cut Wood Pieces: Cut the front, back, sides, and roof pieces according to the dimensions above.

Create Entrance Hole: Depending on the bluebird species you’re targeting, create the appropriate-sized entrance hole.

Assemble the House: Attach the sides to the front and back using screws, leaving the roof unattached for now.

Install the Roof: Attach the roof with screws, ensuring a secure fit.

Drill Mounting Holes: Drill two holes beneath the house for mounting purposes.

Sand Edges: Smooth any rough edges to prevent harm to the birds.

Apply Finish (Optional): If desired, apply a water-based, non-toxic finish to protect the wood and add aesthetic appeal.

How To Make Sure Other Birds Don’t Take Over

If your goal is to attract bluebirds, you should be aware that other cavity-nesting birds might also want to take over the space. To discourage this, consider these strategies:

Entrance Hole Size: Adjust the entrance hole diameter to match the preferences of bluebirds. About an inch and a half is perfect!.

Proper House Placement: Bluebirds prefer houses mounted on poles or posts, whereas other birds may prefer trees. Mounting your house around 4-6 feet high can help.

Sparrow Spookers: Attach these devices near the entrance to deter larger birds like sparrows from entering. Learn more about them – and how to make your own – in this article.

Where To Hang Your Bluebird House

Choosing the right location can significantly impact the success of your bluebird house. Consider these placement tips:

Open Spaces: Bluebirds prefer open areas with few obstructions, like fields, meadows, or golf courses.

Avoid Busy Areas: Avoid hanging the house near high human activity zones or areas with heavy traffic.

Mounting Height: Place the house around 4-6 feet above the ground on a pole or post for safety and easy monitoring.

Direction: Orient the entrance hole away from prevailing winds and direct sunlight.
