NORTH ADAMS, Mass. – Spring is just around the corner. With its arrival, bluebirds will be returning north from their winter migration to the southeastern United States and Mexico. If you’re lucky, they’ll pay a visit to your yard.
While bluebirds likely won’t be dining at a bird feeder (they prefer insects and berries), one way to coax them to visit is to add berry-producing native plants and a source of water such as a birdbath to a garden. To set up a bluebird residence, consider adding a bluebird house.
A homemade bluebird house can be a fun family project. Keep in mind that not just any birdhouse will do. A bluebird house should attract bluebirds and keep them safe.
Starting with the basics, a bluebird house should be made of a suitable wood. Pine works well. Cedar and redwood are also options. Wood should be 3/4- to 1-inch thick.
Be sure not to use treated lumber or plywood, and no paint or stain should be used anywhere on the interior surfaces (the nest box) or around the opening. The exterior can be left unfinished or can be decorated (except around the opening) with latex paint or nontoxic wood sealer.

Assembling a bluebird house can be a fun, winter project for the whole family.
Speaking of the opening, the entry hole should be 1-1/2 inches in diameter. A larger hole can allow predators and unwanted species of birds access to the nest box. Too small a hole will prevent bluebirds from entering.
No perch is necessary. Bluebirds will have no problem entering the birdhouse through the proper sized hole without the aid of a perch to land on. Including a perch may actually make it easier for predators to access the nest box.
In addition, be sure your bluebird house includes a hinged or removable panel on the roof or side to allow access for monitoring and end-of-season cleaning. Other useful features include a small opening for ventilation under the roof’s overhang and drainage holes in the bottom.
Detailed instructions for making a bluebird house can be found on the website of the National Audubon Society at go.uvm.edu/bluebirdbox. Kits with precut parts ready to assemble are available for purchase at many retailers and online.
Once a bluebird house is built, the next step is to find a suitable location. Mounting the bluebird house on a pole is preferable to hanging it in a tree. The pole adds extra security from predators and will give a far better chance of attracting bluebirds to it.

Once finished, a bluebird house should ideally be mounted six feet above ground on a pole or pipe in an open area such as a lawn or a field with the front entrance facing south or east.
Mount the birdhouse on a pole or pipe that will stand about 6 feet above the ground. Position it in an open area such as a lawn or a field. The front of the birdhouse should face south or east.
In addition, to help avoid rain and wind entering the nesting area, angle the entry away from the direction of prevailing winds. Adding a squirrel baffle or similar guard to the pole will help protect against climbing pests and predators such as raccoons and snakes.
Your adventure doesn’t have to end once the bluebird house is finished and installed. Monitoring the house can be an enjoyable and educational ongoing activity for the entire family.
