How can I get birds to use birdhouses in my yard and garden? (2024)

Yards and gardens can provide great habitat for a number of the most common and cherished songbirds in New Hampshire, and installing birdhouses is a way to entice many of these species to take up residence. Although not all songbirds will use birdhouses, species that nest in cavities such as house wrens, Eastern bluebirds, black-capped chickadees, and tree swallows will often use birdhouses that have been properly constructed and placed.

Whether you’re building or purchasing new bird houses, it is important to make sure that they are well constructed. Many birds are choosy when it comes to where they nest, and your birdhouses are more likely to be used if you stick to the following guidelines.

  1. Birdhouses should be constructed of untreated wood and only painted on the exterior. The fumes from paint or pressure treated wood can be harmful to birds.
  2. Incorporate a hinged side that makes it simple to clean. Many species won’t use a birdhouse if it has a nest from a previous year inside, and rodents will often build nests in them during the winter months. Early March is a good time to clean any debris out of birdhouses, long before the songbird breeding season begins.
  3. Entrance holes should be 1 3/8” in diameter or smaller to keep starlings out.
  4. No perches on the front. The only birds that use them are nuisance and non-native starlings and house sparrows.
  5. At least four 1/2” drainage holes in the bottom to allow rain to escape and two 5/8” ventilation holes at the tops of each side (four total).
  6. Sides should enclose the floor to keep rain from entering.
  7. A sloped roof with a 4” overhang in the front and 2” on the side will keep most rain out.
  8. There should be grooves leading to the exit hole on the interior of the box (unless the wood is rough textured) to make it easier for fledglings to get out.

Once you have adequate birdhouses, you’ll want to focus on properly mounting and them. Whenever possible, avoid hanging birdhouses from trees or buildings. Instead, attach them to metal poles, which are much easier to put predator guards (baffles) around. Raccoons, squirrels, and cats will raid nest boxes if they are allowed the opportunity.

Your birdhouse placement will also impact whether they are occupied or not. Try to space birdhouses at least 25’ apart, because some species are territorial and will not allow other birds to nest too close by. Of equal importance is the height of the birdhouse. For most species, bird houses should be at least five feet above the ground, if not higher.

The habitat type near the birdhouse will determine which species might use it. For example, birdhouses that are placed near water are more likely to attract tree swallows, whereas house wrens will use those in gardens. Eastern bluebirds prefer to nest on the edge of open fields, while chickadees like wooded areas.

Make sure to get your birdhouses up as soon as possible in the spring, well before the start of the breeding season. Mid to late March is ideal. If you don’t get your birdhouses up early enough, they may still be used to raise a second brood later in the summer, or the following year.

Remember, there are many other ways to attract birds to your yard besides putting up birdhouses. Planting a wide variety of trees and shrubs, providing a source of clean water, and encouraging insect populations by avoiding the use of unnecessary pesticide applications are all essential aspects of creating a healthy habitat for our feathered friends.

FAQs

How can I get birds to use birdhouses in my yard and garden? ›

Planting a wide variety of trees and shrubs, providing a source of clean water, and encouraging insect populations by avoiding the use of unnecessary pesticide applications are all essential aspects of creating a healthy habitat for our feathered friends.

Why won't birds use my birdhouse? ›

“Placing the birdhouse in the wrong habitat – say, deep woods for a chickadee, or in a very built-up area for bluebirds–will keep them from using the house.” In addition, the bird house should be the right size for the bird you're hoping will use it.

How do birds know to use birdhouses? ›

What type of bird you want to attract will determine where you place a birdhouse. For example, bluebirds will use houses in open fields; chickadees, titmice, and nuthatches all like the open woods and edges; woodpeckers like forest openings and edges; and so on.

What color should a birdhouse be to attract birds? ›

Birds like to live in birdhouses that are camouflaged-colored: grey, green, brown. While attractive to humans, colorful birdhouses can cause lethal harm to birds inhabiting them. Avoid painting the inside of a birdhouse or around the lip of the entrance hole.

What is the best birdhouse to attract birds? ›

The most desirable nesting boxes feature natural wood, ventilation and drainage, privacy, a safe and secure location, an angled roof and a properly-sized entryway.

Where should you not put a birdhouse? ›

Whenever possible, avoid hanging birdhouses from trees or buildings. Instead, attach them to metal poles, which are much easier to put predator guards (baffles) around. Raccoons, squirrels, and cats will raid nest boxes if they are allowed the opportunity.

Where is the best place to put a birdhouse in the garden? ›

The ideal position is a sheltered north or north-easterly aspect. A tree, wall or even a high fence post can be used to secure the nest box too, but generally, the nest box should be at least 1.5 metres above the ground.

Should you put anything in a birdhouse? ›

Many cavity-nesting birds will add their own nest material, but the woodpeckers, waterfowl and owls prefer nest boxes with 2-3 inches of dry sawdust or woodchips in the bottom. Place the box carefully. Put your birdhouse up on a sturdy pole, post, tree, or under a house eave. Freely swinging birdhouses are rarely used.

Will birds sleep in a birdhouse at night? ›

These structures are often thought of as a bird's home base. However, nests are used solely for housing eggs and chicks — not as a place to sleep at night. Once the chicks have left, it's unlikely the nest would be reused.

What time of year do birds use birdhouses? ›

Because birds are already shopping around for nest sites, early spring is a good time to install backyard birdhouses. Not all birds nest and rear their young in houses. Those that do are species that seek out natural cavities in trees.

What direction is best for a birdhouse? ›

First, it is recommended that the birdhouse faces the opposite direction from our prevailing winds. This means, as much as practical, birdhouses should face a northeasterly direction. The height where you place bird boxes should be at least five feet off the ground.

Why won't birds come to my yard? ›

Fluctuating food supplies/requirements.

Also, birds have different dietary needs during different times of the year, so they may move to or away from your feeders seasonally. You may notice fewer birds at your feeders during the late summer and early fall as there is usually lots of natural food available.

Do birds prefer unpainted birdhouses? ›

Most birds have a color preference — some birds like unpainted birdhouses away from direct sunlight, others like a birdhouse painted with light colors and still others prefer bright colors for their birdhouse.

Where is the best place to put a birdhouse? ›

A birdhouse and its entrance hole should face away from prevailing winds. In the United States, it's very common for a birdhouse to face east, which is often faced away from the prevailing wind and the strong afternoon sun.

Do bird houses actually help birds? ›

The oval-shaped entrance helps prevent predators like raccoons from entering. Chickadees, tufted titmice and nuthatches are comfortable with a 1-1/4-inch hole, while bluebirds need about 1-1/2 inches to get inside. Check out these unique birdhouses birds will actually use.

Which direction should a bird box face? ›

The recommended direction to face a nest box is between north and east, as this will provide natural protection from direct sunlight, wind and rain, creating a more suitable and safe environment for growing birds. The box can also be tilted marginally forward to allow any rain to run clear of the entrance.
