How To Keep Other Birds Out Of Bluebird House

Last Updated on June 6, 2023 by

Hey there, fellow bird enthusiasts! Are you tired of other birds taking over your bluebird house? Well, fear not because I am here to share some tips and tricks on how to keep unwanted feathered friends out of your precious bluebird abode.

One of the biggest challenges for bluebird lovers is keeping other cavity-nesting birds from invading their nest boxes. Common culprits include House Sparrows, European Starlings, and Tree Swallows. These birds can cause harm to vulnerable nesting bluebirds by stealing their eggs or even killing their young. So it’s crucial that we take measures to protect our beloved bluebirds from these intruders. With a few simple steps, you can ensure that your bluebird house remains a safe haven for these beautiful creatures. Let’s dive in!

Understanding Cavity-Nesting Bird Behavior

As a bluebird house care expert, it’s important to understand the behavior of cavity-nesting birds. Bluebirds are territorial creatures and will fiercely defend their nesting site from other birds. However, if competing for limited resources like nesting material or food, they may be forced to share space.

It’s essential to provide enough nesting material inside the house so that bluebirds don’t have to compete with other birds for resources. This could include wood shavings, grasses, or even pet hair. The more comfortable the bluebirds feel in their home, the less likely they will be to allow other birds into their territory.

Another way to discourage competition is by placing multiple birdhouses at least 100 feet apart. This allows each pair of bluebirds to establish its own territory without interference from neighboring birds. Additionally, avoid putting up houses near areas where non-native species such as House Sparrows or European Starlings congregate.

Understanding these behaviors can go a long way in keeping unwanted guests out of your bluebird house. Providing ample nesting material and spacing out birdhouses will help ensure your feathered friends have everything they need while maintaining their territorial habits. With proper care and attention, you can create an ideal environment for these beautiful creatures to thrive!

Identifying Common Nesting Intruders

The bluebird house is a charming addition to any garden, but it can attract unwanted guests. Identifying common nesting intruders will help you take steps in keeping them out and ensuring the safety of your feathered friends.

Preventative measures are always better than cure. One effective way to deter larger birds like starlings from taking over the bluebird house is to ensure that its entrance hole size does not exceed 1.5 inches. Additionally, installing baffles or predator guards around the birdhouse can prevent raccoons, snakes, and cats from getting too close.

Squirrels are notorious for stealing eggs and damaging nests. If you notice squirrel activity near your bluebird house, try these deterring methods:

  • Add metal cones or slinky toys around the pole supporting the birdhouse.
  • Coat the pole with petroleum jelly or chili powder.
  • Install an electrified wire just above the baffle so that squirrels cannot climb up without receiving a mild shock.

House sparrows are also known to invade bluebird houses and even kill adult bluebirds. Here are some ways to keep them away:

  • Provide nest boxes specifically designed for house sparrows elsewhere in your yard.
  • Remove their nests as soon as possible if they do manage to infiltrate the bluebird house.
  • Use decoys such as plastic owls or hawks near your garden.

By identifying common nesting intruders and implementing preventative measures and deterring methods, you can protect your beloved bluebirds and enjoy watching them thrive in their cozy abode. Remember that vigilance is key in maintaining a safe environment for our avian friends.

Selecting The Right Bluebird House Design

When it comes to keeping other birds out of your bluebird house, selecting the right design is crucial. Choosing materials that are sturdy and durable will help keep unwanted visitors from entering. Make sure that the entrance hole is only big enough for bluebirds to fit through.

Proper placement of your bluebird house is also important in deterring other birds from nesting inside. Bluebirds prefer open areas with little vegetation or trees nearby. Placing the house on a pole or post can also make it difficult for larger birds to access.

Consider investing in a predator guard, which can further protect your bluebirds from outside threats like squirrels, raccoons, and snakes. These guards attach directly onto the pole or post and prevent predators from climbing up and accessing the nest box.

Overall, selecting a well-designed bluebird house made of quality materials and placed in an appropriate location can greatly reduce the likelihood of other birds attempting to enter. By taking these precautions, you can ensure that your feathered friends have a safe and comfortable place to call home.

Installing A Predator Guard

To ensure the safety of bluebirds in their house, it is important to install a predator guard. A predator guard will help keep other birds and animals from entering the bluebird house and harming its occupants.

There are two main options for installing a predator guard: DIY or purchasing one. If you choose to make your own, there are many tutorials available online that can guide you through the process. Some popular materials used for constructing DIY predator guards include PVC piping and chicken wire.

If you decide to purchase a predator guard, be sure to do some research beforehand. Look for high-quality products made from durable materials that will withstand weather conditions and potential predators. Additionally, consider the size of the predator guard in relation to your specific bluebird house; it should fit snugly around the entrance hole without obstructing it.

Overall, installing a predator guard is an essential step in protecting bluebirds from harm while they inhabit their house. Whether you choose to construct your own or purchase one, take care when selecting materials and sizing so that your feathered friends remain safe and secure.

  • Four recommended types of material for making DIY predator guards:
  1. Galvanized steel mesh
  2. Hardware cloth
  3. Aluminum flashing
  4. Plastic drainpipe

Remember that not all materials may work best for every situation and environment.

  • Consider adding multiple layers of protection with additional elements such as motion sensors or alarms.

  • Consult with local birdwatchers or conservationists for advice on which type of predator control system works best in your area.

  • Regular maintenance checks are necessary to ensure continued effectiveness of the installed predator guards over time.

Monitoring Nesting Activity

It’s important to record when the bluebirds are nesting, so you can keep an eye on their activity. Watching for predators is also key, so you can scare them away if needed. Lastly, it’s a good idea to note any behaviors you observe, as that can help inform future decisions. I always recommend taking a few minutes each day to check on the bluebirds and their house. That way, you can spot any potential problems early on. Pay attention to when they’re arriving and leaving, as that can tell you a lot about their nesting activity. Also, if you see any unusual behavior, it’s best to investigate it right away. That way, you can ensure your bluebirds are safe and happy!

Record Nesting Times

Hey there bird lovers! Are you tired of other birds taking over your bluebird house? Well, fear not because I am here to share some tips on how to keep those pesky intruders out.

One way to ensure that only bluebirds are nesting in your box is by tracking their progress. By keeping an eye on the activity inside the nest, you can determine if it’s a bluebird or another species trying to take up residence. Not only does this help with monitoring but also keeps data collection organized and efficient.

Another helpful tip is to record nesting times. Bluebirds typically start building nests in early spring, so if you notice any activity outside of this time frame, it may be from another bird species looking for shelter. By recording these times, you’ll have a better understanding of what kind of birds are attracted to your box and when they’re most active.

Lastly, make sure to check regularly for signs of occupancy. If multiple types of birds are entering the house at different intervals throughout the day, then it’s likely not being used as intended. Keep an open mind about which species could potentially use the space and track their visits over time. This will provide valuable information that can be used to optimize future nesting seasons.

In conclusion (oops! Sorry!), maintaining a healthy environment for bluebirds means paying attention to details like tracking progress and collecting data through recording nesting times. With these tips in mind, you’ll have no problem keeping other birds out of your beloved bluebird house. Happy bird watching!

Watch For Predators

Hey there, fellow bluebird enthusiasts! Now that we’ve talked about tracking progress and recording nesting times, it’s time to discuss another important aspect of monitoring your bluebird house: watching for predators.

Unfortunately, many animals see the bluebird house as an easy target for a meal or shelter. This includes snakes, raccoons, cats, and even squirrels. To prevent these predators from accessing the nest box, consider installing a baffle around the pole or post supporting the box. This will make it difficult for any animal to climb up and reach the entrance hole.

Another way to deter predators is by using decoys. Placing fake owls or hawks near the birdhouse can scare away animals that would otherwise try to get inside. However, be sure to move the decoys occasionally so they don’t become familiar to other creatures in the area.

It’s also essential to check regularly for signs of predator activity. If you notice scratches on the outside of the box or feathers scattered nearby, it could mean that a predator has already attacked. In this case, remove any debris and monitor more closely going forward.

In summary, keeping predators at bay is crucial for ensuring a safe environment for our beloved bluebirds. Consider installing baffles and using decoys while also checking frequently for signs of harm done by predators around your birdhouse. With these tips in mind along with those previously discussed regarding tracking progress and collecting data through recording nesting times- you’ll have no problem providing a healthy home for your feathered friends!

Note Bird Behavior

Hey there, fellow bluebird enthusiasts! We’ve already talked about the importance of tracking progress, recording nesting times, and watching for predators to ensure a safe environment for our feathered friends. Now it’s time to discuss another crucial aspect of monitoring your bluebird house: noting bird behavior.

Observing habits is an effective way to understand ecology and determine how well your bluebirds are adapting to their surroundings. For instance, by taking note of the birds’ feeding patterns and vocalizations, you can gain insight into their diet preferences and social interactions. You may also want to observe how often they leave the nest and whether or not they return with food in their beaks.

Another critical factor to consider when observing bird behavior is any unusual activity around your bluebird house. If you notice that the birds seem particularly skittish or agitated, it could indicate a predator nearby or some other disturbance. Alternatively, if the birds appear calm and comfortable in their surroundings, this suggests that they feel safe and secure in their home.

Finally, remember that observing bird behavior requires patience and consistency over time. It’s essential not to disturb the birds too much during observation periods as this can cause stress and anxiety leading them away from the box. Instead, try setting up a discreet viewing area where you can watch without disturbing them while still being close enough for detailed observations.

In summary, understanding your bluebirds’ habits through careful observation is key to maintaining a healthy ecosystem around your birdhouse. By noting behavioral patterns like feeding habits, vocalizations responses; we have insights on changes before any harm gets done—observing these behaviors consistently without causing undue stress on our feathered friends ultimately helps us keep better care of them over time!

Discouraging Unwanted Visitors With Physical Deterrents

Are you tired of other birds invading your bluebird house? Don’t worry, there are ways to discourage unwanted visitors with physical deterrents. Scare tactics and decoy options can be effective in keeping other birds out.

Scare tactics involve using visual or auditory stimuli to frighten birds away from the bluebird house. One option is to hang shiny objects like CDs or aluminum foil near the entrance of the house. The reflection will startle birds and make them think twice about entering. Another method is to play recordings of predator calls such as hawks or owls near the birdhouse. This will mimic natural sounds that signal danger and scare off potential invaders.

Decoy options also work well in deterring unwanted guests. Placing fake predators like plastic snakes or owls on nearby branches can trick birds into believing there is a real threat nearby. Additionally, placing nesting materials specific to certain bird species around the area can attract those types of birds while dissuading others.

Here’s a helpful table outlining some physical deterrent methods:

Deterrent Pros Cons
Shiny Objects Inexpensive, easy to find May not deter all bird species
Predator Recordings Mimic natural sounds, effective against many bird species Can disturb neighbors if played too loudly
Fake Predators Highly effective in scaring birds away More expensive than other methods

Remember, it’s important to regularly check on your bluebird house and remove any nests that don’t belong there. With these physical deterrents in place, you’ll be able to keep your bluebirds safe and happy without worrying about unwelcome guests disrupting their home.

Providing Alternative Nesting Sites

I’m a bluebird house care expert, and today I’d like to talk about providing alternative nesting sites. One way to do this is by providing nest boxes. This can provide a safe, secure option for bluebirds, and keep other birds out. Building shelters is another great way to give bluebirds a safe place to nest. You can also plant trees that provide plenty of shelter and food, so that bluebirds have a natural place to nest. All of these are great options for providing alternative nesting sites for bluebirds.

Providing Nest Boxes

Picture this: a beautiful bluebird gliding through the air, searching for the perfect place to build its nest. As humans, we can help these magnificent birds by providing them with suitable nesting sites such as DIY nest boxes. These boxes should be designed specifically for bluebirds and placed in open areas where they are visible but not too exposed.

As a bluebird house care expert, I highly recommend using natural nesting materials when constructing DIY nest boxes. Bluebirds prefer soft materials like pine needles, grasses, and feathers which will provide comfort to their young ones during harsh weather conditions. You can make use of dried leaves or even hair clippings from your furry pets! Remember that it is important to avoid synthetic materials as they may cause harm to the birds.

It is essential to understand that other bird species may try to invade bluebird houses if they perceive them as vacant properties. To prevent this from happening, install predator guards on poles or trees where you hang your DIY nest box. Not only will these guards keep predators away, but they also discourage other birds who might want to enter the box.

In conclusion, providing alternative nesting sites plays a crucial role in preserving our avian friends’ population. With simple efforts like building DIY nest boxes and incorporating natural nesting materials while taking measures against predators and intruders- we can ensure that our skies remain filled with chirping melodies of these wonderful creatures for generations to come!

Building Shelters

Attracting bluebirds is a delightful activity that can be accomplished by providing suitable nesting sites. Bluebirds are highly sought-after due to their vibrant colors and beautiful songs, making them an excellent addition to any backyard birdwatcher’s collection. One way to attract these birds is by building shelters such as DIY nest boxes that mimic the natural environment where they usually reside.

When it comes to choosing nesting materials for your DIY nest box, it is crucial to keep in mind what bluebirds prefer. These birds have specific preferences when it comes to the texture and softness of their nests. Pine needles, grasses, feathers, dried leaves, and even pet hair clippings make great choices for natural nesting materials. It is essential to avoid using synthetic materials as they may harm or discourage bluebirds from using the house.

Building shelters not only attracts bluebirds but also provides other benefits such as protection against harsh weather conditions and predators. The design of the shelter should include predator guards on poles or trees where you hang your DIY nest box. This will help prevent intruders like squirrels and raccoons who might try to invade the house.

In summary, attracting bluebirds requires effort and knowledge about their preferred habitats and nesting materials. Building shelters such as DIY nest boxes with natural nesting materials while taking measures against predators ensures that our avian friends can thrive peacefully in our backyards without fear of danger or discomfort.

Planting Trees

Now that we’ve discussed the importance of DIY nest boxes, it’s time to explore another way to provide alternative nesting sites for bluebirds – planting trees. As a bluebird house care expert, I highly recommend planting the best tree species in optimal locations.

When selecting the best tree species for bluebirds, consider those that provide suitable nesting and feeding opportunities. Eastern red cedar, American holly, and dogwood are some excellent choices. These trees offer berries and insects that attract bluebirds while providing them with natural shelter from harsh weather conditions.

Optimal planting locations can also play a significant role in attracting bluebirds. Planting these trees near water sources like ponds or streams is ideal as they prefer habitats close to water bodies. Additionally, open areas such as fields or meadows where there is plenty of sunlight allow for easy access to food and safety from predators.

It is essential to note that proper maintenance is necessary when planting trees for bluebirds. Pruning branches regularly ensures adequate airflow while preventing overcrowding of leaves around their nests. Also, avoid using pesticides or harmful chemicals on these trees as they may harm not only the birds but other organisms living nearby.

In conclusion, providing alternative nesting sites through tree planting offers many benefits for bluebird conservation efforts. By choosing the best tree species and optimal planting locations while practicing proper maintenance techniques, we can encourage more bluebirds to thrive in our backyards.

Seeking Professional Assistance When Necessary

After providing alternative nesting sites, another important aspect of bluebird house care is keeping other birds out. While some bird species may seem harmless to the bluebirds, they can actually compete for food and resources, and even harm or kill the young chicks. Therefore, it’s crucial to take measures to keep them away.

  1. Install a predator guard: This can be in the form of metal plates or cones that prevent climbing predators such as raccoons and snakes from reaching the nest box entrance. These guards should be at least 2 feet off the ground and have no branches or structures nearby that could provide access.

  2. Use an appropriate size hole guard: Some larger birds like starlings may try to enter through the entry hole, so installing a wire mesh around it can prevent them from getting inside while allowing smaller bluebirds to enter without trouble.

  3. Place deterrents near the box: You can use visual or auditory cues such as reflective tape, wind chimes, or fake owls to scare off potential intruders. Be careful not to disturb your bluebirds with loud noises though!

  4. Clean regularly: Keeping your box clean and free of debris will discourage other birds from using it as well as reduce the risk of disease transmission between different bird species.

Despite taking these precautions, sometimes other birds still manage to get into your bluebird house. When this happens, it’s essential to act quickly before any damage is done.

When to consult expert advice? If you’re having persistent problems with non-native bird species invading your boxes despite all efforts taken above then seeking professional assistance might be necessary. An experienced wildlife biologist or ornithologist can help identify which specific type(s) of birds are causing issues and recommend effective solutions tailored specifically for your situation.

Taking steps to exclude unwanted visitors from your bluebird house not only protects your feathered friends but also helps ensure successful breeding seasons year after year! Remember that prevention is key, but if you do encounter problems, don’t hesitate to seek expert advice before it’s too late.


As a bluebird house care expert, I understand the importance of keeping unwanted visitors out of your precious nesting site. By following these tips and tricks, you can ensure the safety and comfort of your resident bluebirds.

However, it’s important to remember that even with all precautions taken, nature can be unpredictable. Always keep an eye on the activity in and around your bluebird house. And if at any point you feel overwhelmed or unsure about how to proceed, don’t hesitate to seek professional assistance from a local birding organization or wildlife rehabilitator. With patience and perseverance, you can create a welcoming home for your feathered friends while protecting them from potential intruders. Happy bird watching!
