We discussed the "Problems with Heat and BluebirdBoxes" on our other bluebirdhouse plans page. It also makes for easy assembly in minutes with a power or hand held screwdriver. It makes for easy assembly in minutes with a power or hand held screwdriver.
Convection Keeps The Birdhouse Cool
You can leave the ends square, or cut them at 63 degrees (with your circular saw set at 27 degrees) as we did. Top of sides are attached to the inner roof above the entry hole. Natural cavities are usually is such short supply, that birds usually startinvestigating them almost immediately after they are put up. Dead trees are quickly cut down and removed from our parks and yardsbecause we don't want falling trees to damage property or to hurt someone. Conley Black states outright that temperatures that exceed 107 F willkill bluebird eggs andchicks.
Thanks to many dedicated people building nest boxes, bluebirds have recovered!
I hope you have enjoyed my definitive guide to bluebird houses! At over 4,000 words, it’s one of the longest posts you will find on Bird Watching HQ. It can get extremely hot inside of a bluebird nest box. Your birds will appreciate some holes drilled into the top to help with airflow and cooling.

Also note, the size bits you use may differ from mine. Then, carefully hammer 6 nails into the back of the birdhouse (3 in each side). Carefully center the back of the birdhouse (I use my fingers). Note that you can either center the back so that it overhangs the top and bottom edges. Or, if mounting to a pole or T-Post, you can align the top to the back, to the top of the sides. But let's think a minute about why we want to build a bird house and what we hopeto accomplish.
As a minimum, the houses should be cleaned and repaired in early February each year. Did you know that up to six pairs of bluebirds will nest per acre and raise multiple broods per season if proper habitat can be established? We found that understanding their habitat needs and issues is fundamental to building successful bluebird habitat.

The easiest way to fix this problem is to add a guard or extend the hole to make it harder for hawks, cats, and other predators to reach inside. The BEST way to make sure that House Sparrows don’t take over your bluebird boxes is to CONSTANTLY monitor them at least ONCE per week. By checking the boxes so often, you can identify and rectify any problems quickly. Use a 1 1/2″ spade bit to drill the entrance hole as shown on illustration above.
These guards are not hard to make, and can add another layer of defense to the birdhouse. It isn’t too hard to find examples of tragedy where the mother and babies were killed because predators entered. Then, position the parts so that you can drive two nails into each side of the birdhouse and secure the floor. I’m using 4d 1-1/2″ box nails that are galvanized (exterior). They have a small shank which makes them less likely to cause splitting of the wood. To further reduce the chances of the wood splitting, blunt the tips with your hammer.
So, placing bluebird nesting boxes in appropriate locations, deterring predators, and preventing competition from sparrows and starlings can greatly promote successful bluebird habitats. Preventing starlings is easy, simply make the next box opening 1 ½” in diameter and the starling will be too big to enter the house. For sparrows, it’s necessary to inspect the houses on a regular basis and clean out any sparrow nests before they get established. Predators can be deterred by locating a baffle below the nesting box on the mounting pole. Bluebird houses should be installed in late fall or early spring.
Since Tree Swallows commonly nest in bluebird houses,many people assumed the two species need the same size box. Hummingbirds do not use birdhouses as they prefer to build their nests on the branches of trees and shrubs and not in enclosed tree cavities - or in equivalent enclosed bird houses. Dan Sparks and other members of the North American Bluebird Society (NABS) designed this updated bluebird nesting box.
If you are worried about cutting straight, then I’ve got good news. This saw cuts on the pull stroke, making it way easier to cut a straight line! I’ve got a link to the same saw I used to build this birdhouse at our Recommended Products Page. But cut the boards from the cedar picket slowly and carefully. The more square and true your cuts are the easier the birdhouse will go together. And, the more secure and sturdy the birdhouse will be.
The main components of the system are a 5 foot long section of ½” electrical conduit and a 48” long piece of ½” diameter reinforcing bar (or rebar for short). These can easily be purchased at most home centers for a few dollars. The other hardware needed is a ½” EMT coupling with one ¾” screw to replace the shorter one at the bottom and possibly one or two ½” conduit straps to secure the top of the hole to the house. The houses should be cleaned and in place by February each year to attract migrating bluebirds for bluebird nesting season. Leave them up year-round, since overwintering bluebirds use them for roosting.
This allows the crafts person to feel and better judge appropriate hole sizes and snugness to prevent stripping and splitting wood. We hope your hard work is rewarded with three successful clutches ofbluebirds this nesting season. We have measured temperatures inside empty bird nest boxes above 105� F onseveral occasions. Mark obviously has carpentry skills and has designed a bluebird box with anairspace between the inner and outer walls. Make pilot holes slightly larger in the primary work piece (first piece in which the screw is inserted) such that screws can be turned in easily without leaving room for movement.
If you build and mount them correctly, a bluebird nest box can deter competing species and predators. In this plan, the bird hole size measures 2 ¼ inches in diameter. It is an easy DIY birdhouse given the right tools available. There are 2 pivot nails allowing side swing out for easy cleaning.
Mountain bluebirds need a larger (1-1/2-in. x 2-1/4-in.) entry hole. The bluebird nesting box plan shown below was designed to meet bluebird requirements, provide easy access for cleaning, and should last many years. Use durable one-inch thick boards (such as cedar) and wood screws for construction, and it’s unnecessary to paint the house.
I used the samepaddle bit with which I cut the entrance holes in the outer and inner boxes tofashion an air seal using a piece of wood that was the right thickness(picture). For the side vents I found a piece of a long plastic funnel I nolonger needed which happened to be �� in diameter. Build the eastern bluebird birdhouse with red cedar, pine, or almost any soft wood. Use wood rough-cut on both sides so that birds can grip both interior and exterior surfaces. The trees surrounding the farm fields seem to give them an ideal habitat – old natural cavities for nesting and perches perfect for preying on insects in the field. We often see numerous bluebirds of varying ages while we’re out working in the field or garden during the spring, summer, and fall.
Unfortunately, there is still a lot more you can learn about maintaining bluebirds, specifically if you want to set up your own bluebird trail. I like the one pictured above because it includes copper around the entrance hole, which makes it impossible for any mammal to chew to enlarge the hole. The oval hole is optional depending on your preference. A 1 and 9/16-inch hole must be used wherein the ranges for Western or Eastern Bluebirds are overlapping with Mountain Bluebirds. The finished project looks great and will undoubtedly make a fine home for a young Bluebird family.
