How to Choose a Bird House (birdhouse)

Birdhouses, also known as nesting boxes, provide safe havens for birds to build their nests and raise their young. By offering a suitable birdhouse in your garden or backyard, you attract feathered friends and contribute to the conservation of various bird species. However, deciding which is best for your avian visitors can be overwhelming with a wide range of birdhouses available. In this article, we'll guide you through the essential factors to consider when choosing the perfect birdhouse.

1. Species-Specific Design

Different bird species have varying preferences regarding nesting habitats. You can research the types of birds common in your area and choose a birdhouse to attract them. Different species may require specific entrance hole sizes, cavity depths, and interior dimensions. For instance, a bluebird house will differ from a chickadee or a wren house in terms of dimensions and specifications.

Dude, it'll fit

I've had the following birdhouse for years. It has the following features: 1.25” (3.2cm) hole, ventilation, clean ability, and a durable cedar structure. It has the right hole size for wrens and chickadees and other small birds. If you are wondering if the wren in the picture was able to fit that stick in the whole. Sadly, it didn't, but it didn't deter him from trying larger sticks.

2. Material

Bird houses come in various materials, each with its advantages and considerations:

• Wood: Wooden bird houses are traditional and aesthetically pleasing. Cedar and cypress are excellent choices as they are durable and weather-resistant.
• Metal: Metal bird houses are more durable and can deter predators, but they may become hot in direct sunlight.
• Recycled Plastic: Environmentally friendly and easy to clean, recycled plastic birdhouses are lightweight and resistant to decay.
• Ceramic or Clay: These birdhouses have natural insulating properties but can be fragile and may require proper weatherproofing.

Consider the pros and cons of each material and select one that suits the needs of the birds and the prevailing weather conditions in your area.

3. Entrance Hole Size

The entrance hole size of the birdhouse is crucial in determining which bird species can use it. Smaller birds, such as chickadees and wrens, require smaller entrance holes to keep out larger, more aggressive species. Research the specific birds you want to attract to ensure the hole size is appropriate for them.

• Bluebird 1.5” (3.8 cm)
• Chickadee 1.25” (3.2cm)
• Flicker 2.5” (6.35cm)
• House Finch 2” (5.1cm)
• House Sparrow 1.75″ (4.5cm)
• Kestrel 3” (7.6cm)
• Nuthatches 1.25” (3.2cm)
• Owl 6” (15cm)
• Purple Martin 2.5” (6.35cm)
• Tree Swallow 1.5” (3.8cm)
• Warbler 1.25”
• Woodpecker 1.25” (3.2cm)
• Wren 1.25” (3.2cm)

Note: If you have a birdhouse with a hole that is too large, you can use a predator guard to limit the access to the correct bird size.

Nature sometimes has the opposite problem.

This house is was created by a local Boy Scouts troop for a nesting pair of American Kestrels. In this case, the small wren with a large attitude (wren-itude) took the larger falcon’s home. Thankfully, the falcons are nesting near by.

4. Ventilation and Drainage

A well-designed birdhouse should have proper ventilation to regulate the temperature inside and prevent the build-up of harmful mold. Additionally, drainage holes in the bottom of the birdhouse are essential to allow rainwater to escape, keeping the nesting area dry.

5. Mounting and Placement

Consider how you will mount the birdhouse. Some birdhouses have built-in mounting brackets, while others require separate hardware. Ensure the mounting method is secure and will withstand wind and other elements.

Regarding placement, choose a location attractive to birds. Most prefer bird houses around 5 to 15 feet above the ground. Avoid placing the birdhouse too close to bird feeders or high-traffic areas, as birds prefer privacy and quiet when nesting.

6. Predator Guards

Predator guards are essential features that help protect nesting birds and their eggs from predators like squirrels, raccoons, and snakes. These guards can be baffles or extended roofs that prevent access to the entrance hole.

As stated above: If you have a birdhouse with a hole that is too large, you can use a predator guard to limit the access to the correct bird size.

Predator guards provide durability to the entrance hole and needed defense for the babies inside.

7. Easy Access for Cleaning

Regular cleaning of birdhouses is crucial for the health and safety of nesting birds. Choose a birdhouse design that allows easy access for cleaning. Houses with hinged roofs or removable panels make the task much simpler.

8. Avoid Perches

Contrary to popular belief, birdhouses do not need perches outside the entrance hole. Perches may attract unwanted visitors and predators. Most cavity-nesting birds can easily enter the birdhouse without the need for perches.

9. Observe Local Regulations

Before installing a birdhouse, familiarize yourself with any local regulations or laws regarding birdhouses and nesting boxes. Some areas may have specific guidelines, especially regarding protected bird species.

10. Provide Additional Resources

While a birdhouse provides a safe nesting place, consider offering other resources to attract and support birds. Plant native trees and shrubs that provide food and shelter. Add a bird bath or fountain nearby to provide a water source, and place bird feeders with appropriate bird food to supplement their diet.

Conclusion

Choosing the right birdhouse involves carefully considering species-specific design, materials, entrance hole size, ventilation, drainage, mounting and placement, predator guards, cleaning access, and adherence to local regulations. By selecting a well-suited birdhouse and providing additional resources, you can create a welcoming habitat for birds, observe their nesting behavior, and contribute to the protection of these beautiful creatures. Enjoy the sight of birds building their nests and raising their young right in your backyard!
