How To Design
Blue Bird House Plans?

There is a Lot to Consider!

How to design blue bird house plans?  The answer is not that simple!

After a couple of weeks of research, I started to write down the considerations important in the design.  There may be other views, but these were the conclusions I reached, and the elements I incorporated into the design shown in the photo.

It took over six versions of the plan before I was satisfied that the most important elements were achieved.

It Needed to be Simple Enough for a Beginner Woodworker to Build!

For other designers this would not be a primary factor, but for me it was!  My hope is to encourage my teenager, other kids, plus adult beginner woodworkers to build these blue bird houses.

That meant avoiding mitered and bevel cuts, or any other step that would scare off those that don't have a lot of woodworking experience.

It Needed to be "One-Board Birdhouse Plans".

I just couldn't make it work with only one size board!  Frustrating.

So the final plan requires two size boards: a 1x10 and a 1x6.

You will notice that the dimensions of this design bird house plans use the full width of the boards (9 1/4" wide for the 1x10, and 5 1/2" wide for the 1x6) on most of the pieces.

It Needed to Keep Out the Rain!

Three designs factors were included to keep out the rain.  The first was a one-piece, large roof.

A large roof is also needed to provide shade.

Since I live in Florida, protecting the nest from both excessive rain, and excessive heat is important.  So a large overhang on both the front and back was necessary.

Because it needed a large roof, using the larger 1x10 became necessary.

The second design element to keep out the rain are kerfs (narrow, shallow cuts) along the edge of the roof to encourage dripping on the outside of nesting box, rather than the inside.

The third design element is an inset floor.  The floor sits 1 1/4" above the bottom of the sides, so that capillary action does not draw water from the sides into the nesting area.

The Blue Bird House Plans Needed Adequate Drainage.

Despite the planning described in the section above, it may not be possible to keep all of the rain out of the bird house.  A drainage system needs to be part of the design blue bird house plans.

The floor of this blue bird house has drainage holes cut across each corner.  Another option would be to drill holes near each corner.

The Design Blue Bird House Plans Needed to Provide for Adequate Ventilation!

If the heat that builds up on a hot summer day cannot escape from the blue bird house, the baby birds could die.

Again, three design elements were included to address the issue of excessive heat.

The first is by creating a larger size floor, giving the fledglings more room to spread out, and stay cool.  The floor of this plan measures 5 1/2" wide by 4 3/4" deep.

The second element are the ventilation holes drilled into both sides of the bird house, near the top.  The plan shows (2) 3/4" holes, but these could vary in size and amount.

The third is building in a a 1/4" gap between side walls and the roof.

The Design Needed to Address Predator Issues!

The baby blue birds are a tasty meal for some birds, cats, squirrels, raccoons and snakes.

This design blue bird house plans incorporates a predator guard at the opening.  This makes it more difficult for other birds to reach in, and it makes it more difficult for the squirrels to chew a wider opening to gain access.

This design also puts the floor 5" away from the bottom of hole, making it more difficult for other predators to reach in and grab the baby blue birds.

Inhibiting predation is huge! Other predators, such as snakes and raccoons, need to be kept away from the blue bird house by proper placement of the house, and by some baffles along the pole.

The Blue Bird House Plans Need a "Fledgling Ladder".

A fledgling ladder is a built in way for the baby birds to climb up to the hole when it is time to leave the nest.

These design blue bird house plans include narrow slits on the inside of the front for just that purpose.  There a many other options that could be used to accomplish the same purpose, such as gluing popsicle sticks horizontally.

What Size Entrance Should the Design Include?

Wow!  There is so much discussion from many experts on blue birds as to the correct size entrance hole, it was confusing.

I eventually settled on a 1 1/2" round hole, which seems to be what most say is the right size for both the Eastern and Western blue bird.

However, if designing for the Mountain blue bird the hole should a little larger.  Some say increase it by 1/8" to  a 1 5/8" hole, and some say increase it by 1/16" to a 1 9/16" hole.

Luckily, each builder of this plan can choose for him or herself what is best for the environment and type of bluebird in their region.

The Blue Bird House Needs to Open for Clean Out.

Taking out the old nesting material is important if you want more than one batch of baby blue birds.

You may also need to open the blue bird house to address any blowfly larvae problems.

The objective with these design blue bird house plans is to make "clean out" as easy as possible.

This plan includes a front panel that swivels down so that the bird house can be easily cleaned out.
