Making a nesting box is a great way to get involved in the bird communities in your area. Nesting boxes make a big difference to local ecosystems, and they’re simple to make.
We’ll discuss everything you need to know about building a nesting box, including what species to expect and how to maintain the box over time.
To make a DIY nesting box for birds, follow these steps:

How To Make a Nesting Box
Building a nesting box is a simple way to increase the likelihood that birds will nest in your area, and it makes for a good afternoon project.
To build a nesting box, follow these steps:
- Gather the appropriate materials. This includes plywood, hardwood, or softwood, tape measure, hammer, nails, drill, and screws. Just make sure that the wood is thick enough to provide significant insulation, about 15 mm (0.59 in).
- Cut the pieces of wood according to this diagram provided by the Royal Society for the Protection of Birds. You should have a floor, roof, two slanted side pieces, a front, and a tall back. The angle of the slanted side pieces and the roof should be about 15 degrees.
- Cut an entry hole about 1 ½ in (38.1 mm) across in the front piece of wood.
- Drill four ventilation holes, two on each side of the nesting box.
- Nail the sides, bottom, front, and back of the box together.
- Consider adding a rubber strip to act as a hinge between the top edge of the roof and the back.
- Attach the roof to the rest of the box using screws. This allows you to swing the roof open to clean out the inside.
- Decorate your box using only water-based paints and other non-toxic supplies.

Birds have different needs according to their size and habitat.
Which Birds Use Which Kinds of Nesting Boxes?
Due to the timber industry, agriculture, and other forms of land development, many birds have seen a decrease in available nesting habitats.
The best way to support these birds is by planting more trees; however, it takes some time for trees to mature to the point that they can provide suitable nesting habitat.
Nesting boxes make for a good short-term solution.
Nesting boxes attract many different birds, each with slightly different needs regarding how the nesting box should be built.
In each case, the nesting box should approximate their natural habitats.
Birds that use nesting boxes include the following:
- Bluebirds: square nesting boxes
- Chickadees: square nesting boxes
- Nuthatches: square nesting boxes
- Titmice: square nesting boxes
- Swallows: square nesting boxes
- Kingfishers: horizontal rectangular nesting boxes
- Rosellas: vertical rectangular nesting boxes
- Ducks: larger than average square nesting boxes
Invasive species that also use nesting boxes include:
- European Starling
- House Sparrow
- Common Myna
Tips for Installing a Nesting Box
Once you’ve built a nesting box, you’ll need to install it. Take these tips into account as you do so.
- Put the nesting box outside sometime just before the start of spring.
- Make sure the nesting box isn’t in direct sunlight.
- Face the box away from the wind.
- Mount the box on a pole, not on a tree or a fence. This makes it harder for predators to reach the nest.
- Consider adding a baffle under the box to keep predators away.
- Place the nesting box under cover if possible.
- Find a low-traffic location for the box, and don’t place it over a doorway or path.
Maintaining a Nesting Box
Once you install your nesting box, remember to care for it so that it remains habitable year to year.
Nesting boxes need to be cleared out every season because parasites can quickly grow in old nests and threaten future inhabitants.
Many birds will avoid using old nests, but when they do, their young become vulnerable to lice, mites, and other pests.
Just make sure that the young have completely fledged before removing nesting material, or else you might rob them of their nest too early.
When you’re cleaning out the bird box or handling it in any way, you should wear gloves. This prevents the spread of parasites and disease.
Keeping It Clean
Between nesting seasons, you should also thoroughly clean the box with bleach and water.
Simply mix nine parts water with one part bleach, then scrub the box with the solution using a scrub brush.
Make sure that the box is thoroughly rinsed and dried before you reinstall it.
Learn which bird species are native in your area; look for non-native or invasive species taking over your nesting boxes.
You may wish to clear the nests early in the season so that native species can move in instead.
You may also find honey bees taking over your nesting boxes.
Like in the case of non-native or invasive species, you’ll want to consider removing the nests so that native birds can use the space.
Once native species have started using your nesting boxes, monitor from a distance and avoid disturbing the nests.
Simply record which birds are using the box, along with whatever other information you can gather without checking the inside of the box.
Why Do Birds Need Nesting Boxes?
Nesting boxes provide a space for birds to build their nests and raise their young in places where tree hollows and other nesting locations are scarce.
Tree hollows take over 100 years to form, so when nesting territory is lost, it takes a long time to reappear.
Due to the loss of old-growth forests, some birds are having difficulty finding habitats. By installing a bird box, you can make it more likely that these birds will thrive.
Birds also use nesting boxes as a place to stay warm and dry during cold months.
If you want to adapt your nesting boxes to make them better roosting spots, you can plug the ventilation holes once it gets cold.
And then turn the entrance door upside down so that the hole is at the bottom.
