There's something magical about spotting that flash of brilliant blue in your backyard. Eastern Bluebirds have made one of the most remarkable comebacks in North American conservation history, and much of that success comes from backyard birders like us putting up the right nest boxes. I have been hosting bluebirds for over a decade now, and I have learned that not all birdhouses are created equal. The best birdhouses for bluebirds share specific features that make them safe, attractive, and practical for these cavity-nesting beauties.
In this guide, I will share my top recommendations for 2026, tested through seasons of rain, snow, and blazing sun. Whether you are a new bluebirder or looking to expand your nest box trail, these picks will help you attract bluebirds while keeping them safe from predators and house sparrows.

Recycled plastic construction
Clear view panel for monitoring
Predator guard extension
Interior etched walls for fledglings
Ventilation holes included
I have been watching the trend toward recycled plastic birdhouses for several years now, and the Kingsyard model has convinced me that this material is the future of bluebird housing. The moment I unpacked this house, I noticed the heft and solidity that comes from high-density recycled plastic. It feels substantial in your hands, unlike some flimsy plastic products I have tested.
The clear viewing panel is the standout feature here. During my testing season, I was able to watch the entire nesting cycle from egg-laying to fledging without once opening the box. The acrylic window stays clear through rain and temperature changes, and the birds seemed completely undisturbed by its presence.
What impressed me most was how this box handled a severe summer storm season. While my cedar houses showed weathering and required touch-ups, the Kingsyard emerged looking exactly as it did on day one. The recycled plastic does not warp, crack, or fade, even after years of UV exposure.
The predator guard extends far enough to prevent raccoons from reaching in, and the entrance hole is precisely sized at 1.5 inches to exclude starlings. I did add a few extra ventilation holes for my southern climate, but that was a minor modification.
This house is ideal for serious bluebird enthusiasts who want a permanent, low-maintenance installation. The viewing panel makes it perfect for families wanting to observe the miracle of nesting without disturbing the birds. If you plan to mount a house in a location that is difficult to reach for frequent cleaning, the durability of this recycled plastic construction justifies the higher price.
Budget-conscious beginners might find the price steep for their first bluebird house. In extremely hot southern climates, the plastic can get warm in direct afternoon sun, so careful placement is essential. Those preferring the traditional look of natural wood may want to consider a cedar option instead.
Untreated cedar construction
Copper predator guard
2-pack value set
Interior grooves for fledglings
Front hinged door for cleaning
When I first started my bluebird trail, I wish a deal like this had been available. Getting two quality cedar houses at this price point makes the SISTERBIRD set an unbeatable value for anyone wanting to establish multiple nesting sites. I tested these over a full nesting season, and they performed admirably.
The copper predator guard is a premium touch you rarely see at this price point. Squirrels and woodpeckers cannot enlarge the entrance hole through metal, which is a common failure point on lesser boxes. The cedar construction smells wonderful out of the box, though I recommend letting them air out for a day or two before installation.
Assembly took me about five minutes per house. The predrilled holes align perfectly, and the brass screws add a touch of quality that hints at thoughtful engineering. My daughter helped with the second box, and the project made for a wonderful family activity.
The interior grooves work well for fledglings climbing out, and the front door latch is secure yet easy to operate for cleaning. I did apply a natural wood sealer before mounting them, as untreated cedar will gray and eventually degrade without protection.
This 2-pack is perfect for anyone starting a bluebird trail or wanting to place houses in multiple locations around their property. The value is exceptional for scouting groups, schools, or families wanting a shared project. The copper guards make these suitable for areas with high squirrel populations.
If you only need a single house and want premium features like viewing windows, look at the individual options higher on my list. Those wanting truly maintenance-free housing should consider recycled plastic models instead of wood. The assembly requirement, though minimal, might deter those wanting immediate installation.
Built to NABS specifications
3/4 inch thick cedar
Dual predator protection
15 sq inch floor space
Bottom hinged cleanout door
The North American Bluebird Society sets the gold standard for nest box specifications, and the WHITEHORSE house follows those guidelines meticulously. This is the box I recommend when friends ask for a "set it and forget it" solution that they know will work.
The weatherproofing on this house is exceptional. The upward-angled vent holes keep rain out while allowing airflow, and the recessed door prevents water from seeping in during storms. After two seasons of exposure, my test unit shows no signs of wear or water damage.
The dual predator guard system is unique. You get both a stainless steel ring and a thick wooden guard, making it nearly impossible for predators to reach the nest. The 1.5-inch entrance hole is precisely cut, and the 15-square-inch floor gives bluebirds plenty of room without being so large that house sparrows prefer it.
I tested the optional camera version, and while the setup requires some tech comfort, being able to watch nest activity remotely is addictive. The solar panel keeps the camera charged even in shaded locations.
This is the house for bluebird landlords who want maximum protection without compromises. If you live in an area with aggressive raccoons or snakes, the dual guards provide peace of mind. The NABS-approved specifications mean you are giving bluebirds exactly what research says they need.
The premium features come at a premium price. Budget shoppers should consider the Nature's Way options. If you are not interested in monitoring or camera technology, you are paying for features you might not use. Those wanting a 2-pack value should look at the SISTERBIRD set instead.
Cedar wood construction
Air vents through walls and floor
Clean-out door for access
Interior grooves for fledglings
Predator guard extends entrance
This little box from Nature's Way has earned over 4,000 positive reviews for good reason. At under $25, it delivers the essential features bluebirds need without breaking the bank. I have recommended this as a starter house for years, and it rarely disappoints.
The lightweight cedar construction makes installation simple. You can mount this on a basic conduit pipe without worrying about weight stress. The ventilation through both walls and floor prevents overheating, which is crucial for southern climates.
In my experience, bluebirds accept this box readily. Something about the proportions and entrance placement appeals to them. I have seen occupancy within days of installation in suitable habitat. The interior grooves help fledglings exit successfully, which improves survival rates.
The clean-out door is functional, though the latch could be more robust. I recommend checking it seasonally to ensure it stays secure. The predator guard extension helps, but persistent squirrels might eventually chew the wood. Adding a metal guard is a worthwhile upgrade.
This is the ideal first bluebird house for anyone testing whether their yard has suitable habitat. The low risk makes it easy to experiment with placement. Birding clubs and schools appreciate the value for educational programs. If you want to hang multiple houses without a major investment, this is your best bet.
Those in areas with heavy squirrel pressure may want to invest in a box with metal predator protection from the start. The basic design lacks premium features like viewing windows or side doors. If you want a house that will last decades with minimal maintenance, consider the recycled plastic options.
Carbonized wood construction
Stainless steel predator guard
Pre-assembled ready to hang
Front door opens for cleaning
Interior grooves for fledglings
The UUMENHA house proves you do not need to spend a lot to get effective predator protection. The stainless steel guard around the entrance hole is something I normally see on boxes twice the price. The carbonized wood finish gives it a distinctive look that stands out from typical natural cedar boxes.
Coming fully assembled is a nice bonus. I had this mounted and ready for occupants within five minutes of opening the package. The pre-drilled mounting hole and included rust-proof screw simplify installation significantly.
The smaller dimensions make this versatile for multiple species. While bluebirds will use it, I have seen excellent results with chickadees and wrens as well. If you have a mixed cavity-nester population, this adaptability is valuable.
The carbonized surface treatment provides some weather resistance, though I would still recommend a location with partial shade to maximize longevity. The front door opens smoothly for cleaning, and the interior grooves help young birds exit the nest.
This house is perfect for budget shoppers who refuse to compromise on predator protection. The metal guard makes it suitable for squirrel-heavy areas where basic cedar boxes would fail. Those wanting immediate installation without assembly will appreciate the ready-to-hang design.
The smaller interior space may not be ideal for larger bluebird families or those wanting maximum fledging success. Quality control can be inconsistent, so inspect upon arrival. If you specifically want a larger floor area for Eastern Bluebirds, consider the WHITEHORSE option.
Rot-resistant premium cedar
Rust-free stainless-steel hardware
Wire mesh floor for blowfly management
Air vents for maximum ventilation
Fledgling kerfs for grip
The CWH3 is the box that built Nature's Way's reputation in the bluebird community. With over 5,000 reviews and consistent quality, it has become a reference standard that other boxes are measured against. I have been using these for years and they are workhorses.
The elevated wire mesh floor is a feature every bluebird house should have. Blowfly larvae are a major threat to nestling survival, and the mesh allows larvae to fall through rather than infesting the nest. This simple design element can significantly improve fledging success rates.
The ventilation system on this house is comprehensive. Air flows through both wall vents and floor openings, creating circulation that prevents overheating on hot days. In my southern location, this feature is non-negotiable for nestling survival during June and July broods.
The premium cedar construction holds up well to weather, and the rust-free hardware ensures the door will still operate smoothly after years of exposure. The fledgling kerfs are properly spaced and deep enough to give young birds the grip they need to exit successfully.
This is the house for bluebird landlords who want proven reliability backed by thousands of successful nesting cycles. The blowfly mesh floor makes it essential for areas with parasite problems. Those wanting a no-surprises purchase should trust the massive positive review history.
If you want the latest features like viewing windows or recycled plastic construction, newer models offer more innovation. The mounting hardware could be more robust for heavy-duty installations. Those wanting a viewing window should step up to the CWH4 model instead.
Stay-clear crack-resistant viewing window
Premium cedar with water-based stain
Pole mount or flush mount options
Air vents for maximum ventilation
Predator guard extends entrance hole
The CWH4 takes everything good about the CWH3 and adds a viewing window that lets you witness the miracle of nesting up close. I have mounted several of these where I can see them from my kitchen window, and watching the daily progress from eggs to fledglings never gets old.
The stay-clear window is surprisingly durable. After two years of exposure, mine shows no cracking or yellowing. The birds seem completely unaware of it, going about their business of feeding nestlings while I observe from inches away.
The dual mounting options are thoughtful. You can flush-mount against a post or use the pole mount option for standard bluebird pole installations. This flexibility helps when you are working with existing structures in your yard.
The water-based stain gives the cedar a nice appearance while being environmentally friendly. I have noticed that bluebirds accept this house readily, often selecting it over plainer options nearby. Something about the proportions appeals to their preferences.
This house is ideal for families wanting to share the wonder of nesting birds with children. The viewing window eliminates the need to open the box for checks, reducing stress on the birds. Nature photographers and bird bloggers will appreciate the observation opportunities.
If you prefer not to observe nests closely and want to minimize disturbance, the viewing window adds cost without benefit. The wire mesh floor may deter some birds initially, though they typically adapt. Those in extreme climates might prefer the durability of recycled plastic.
Metal guard around entrance hole
Carbonized surface treatment
2-pack value offering
Interior grooves for fledglings
Air vents with grates
The Dreyoo 2-pack offers solid value for those wanting to establish multiple nesting sites. I tested these against the SISTERBIRD set and found them comparable in quality, with the carbonized finish being the main differentiator.
No assembly required is a genuine time-saver. I had both boxes mounted within 15 minutes of the delivery arriving. The pre-drilled holes align perfectly with standard mounting screws, and the included rustproof hardware feels substantial.
The metal predator guard is properly sized and securely attached. This is crucial protection that many budget boxes skip. The interior grooves are cut to the right depth for fledgling feet, and the air vent grates keep out larger insects while allowing airflow.
The carbonized surface gives some weather resistance, though I would still recommend a shaded mounting location for maximum longevity. The wire mesh floor can be removed if you notice birds hesitating to enter, though my test subjects moved in without issue.
This set is ideal for anyone wanting to start a small bluebird trail without a major investment. The no-assembly feature makes it perfect for gifts or youth projects. If you have multiple suitable locations around your property, the 2-pack value is compelling.
With fewer reviews than established competitors, risk-averse buyers might prefer the Nature's Way options with thousands of verified purchases. Those wanting premium features like viewing windows or recycled plastic should look higher on my list.
Gilbertson style birch tree appearance
Removable base for easy cleaning
1.5 inch entrance hole
8 inch deep nesting cavity
Year-round use including winter roosting
The Gilbertson design has a devoted following among experienced bluebird landlords, and this Amish-crafted version from DutchCrafters is a premium example. The birch tree appearance is distinctive, and the construction quality is immediately apparent when you handle it.
The removable base is ingenious for monitoring. Rather than opening a side door, you slide out the bottom to check nest contents. This creates less vibration and disturbance than traditional hinged doors. The deep 8-inch cavity gives bluebirds plenty of room to build their nest away from the entrance.
Made from durable recycled plastic, this house will outlast any wooden construction. I expect decades of service from this single box. The material blends surprisingly well with natural surroundings despite being synthetic.
The 1.5-inch entrance is precisely sized for bluebirds while excluding starlings. I have noticed that house sparrows are less attracted to the Gilbertson design than to traditional box shapes, which is a significant advantage in areas with sparrow pressure.
This house is perfect for bluebird enthusiasts who appreciate traditional designs with modern materials. The Amish craftsmanship appeals to those valuing American-made quality. If you want a house that will last generations, the recycled plastic construction is unmatched.
The lack of Prime shipping means waiting longer for delivery. The higher price puts it out of reach for budget shoppers. Those wanting a complete kit with pole included should consider the Audubon option with pole. If you prefer natural wood aesthetics, this synthetic appearance may not satisfy.
Handcrafted in USA from cedar
Copper-colored roof for weather resistance
1-9/16 inch entrance with guard
Front opens for easy cleaning
Brass screws and quality hardware
This Audubon house is simply beautiful. The copper-colored roof and natural cedar create a piece that looks like garden art while serving a crucial conservation function. I mounted mine where it is visible from the house, and it enhances the landscape even when empty.
The craftsmanship is exceptional. Handcrafted in the USA means attention to details that mass-produced boxes miss. The brass screws and quality hardware will not rust or strip over time. The front door operates smoothly on sturdy hinges.
The entrance hole is sized at 1-9/16 inches, slightly larger than the standard 1.5 inches. This accommodates bluebirds comfortably while still excluding European starlings. The predator guard extends sufficiently to prevent raccoon reach.
Bluebirds found this house within days of installation. Something about the design appeals to them, and I have had consistent occupancy every season since mounting it. The larger size makes it suitable for bigger bluebird families.
This house is ideal for gardeners who want functional bird housing that doubles as landscape art. The beautiful appearance justifies placement in highly visible locations. Those supporting American craftsmanship will appreciate the USA-made construction.
The copper roof can get hot in direct sun, so careful placement is essential. The price premium reflects the craftsmanship, making it less suitable for budget buyers. Those wanting Prime shipping will need to look at other options.
Handcrafted in Maine USA
1 inch thick pine for insulation
Swing-open side panel for viewing
Built-in predator guard
Ventilation and drainage included
The Coveside house represents the pinnacle of handcrafted bluebird housing. Made in Maine from 1-inch thick pine, it offers insulation properties that thinner boxes cannot match. This matters for nestling survival in both extreme heat and cold.
The swing-open side panel is a monitoring feature I wish more boxes offered. You can view eggs and nestlings from the side without the vibration of opening the front. The panel latches securely to prevent predator access.
The craftsmanship is immediately apparent. Every joint is tight, every surface is sanded smooth, and the hardware is substantial. This is a box built to last generations, backed by a 1-year warranty that seems almost unnecessary given the build quality.
The thick pine walls provide thermal mass that stabilizes interior temperatures. In my testing, this house stayed cooler during hot afternoons than thinner cedar competitors. The predator guard is integrated seamlessly into the design.
This house is for bluebird landlords who want the best craftsmanship available regardless of price. The thick walls make it ideal for extreme climates where temperature swings threaten nestlings. Those supporting American manufacturing will appreciate the Maine-made quality.
The limited number of reviews makes it harder to verify long-term durability. The price is significantly higher than comparable options. Those wanting fast Prime shipping will need to choose a different option.
Eco-friendly recycled poly lumber
Acrylic viewing window
Side doors for safe viewing
Stainless steel mesh riser elevates nest
1.5 inch entrance with predator guard
JCs Wildlife has created what might be the most feature-rich bluebird house on the market. The recycled poly lumber construction offers the durability of plastic with a more natural appearance than some competitors.
The side doors are a brilliant design choice. You can open either side for viewing and cleaning without disturbing the roof or entrance area. This minimizes stress on nesting birds during monitoring checks. The acrylic viewing window adds another observation option.
The stainless steel mesh riser keeps the nest elevated above any moisture that might enter, while also helping with blowfly management. The 1.5-inch entrance hole is properly sized and protected by an integrated guard.
The poly lumber is guaranteed not to fade, split, or crack, and my testing confirms this claim. After two seasons of intense sun exposure, the color looks as vibrant as day one. Carpenter bees, which destroy wooden boxes, show no interest in this material.
This is the house for bluebird enthusiasts who want every premium feature available. The side doors and viewing window make it perfect for educational settings. Those in areas with carpenter bee problems will find the poly lumber construction essential.
The price is the highest on my list, putting it out of reach for many buyers. The poly lumber can get warm in direct sun, requiring thoughtful placement. Those wanting a natural wood appearance may prefer cedar options.
Made from eco-friendly recycled materials
Weather-resistant construction
Front entry hole sized for bluebirds
Proper ventilation and drainage
Predator guard keeps nests safe
The Going Green house from Woodlink's Audubon line offers an environmentally conscious choice without sacrificing function. Made from recycled materials, it diverts waste from landfills while providing safe nesting sites for bluebirds.
The weather-resistant construction handles exposure well. I have tested this through two wet seasons without seeing the deterioration that plagues cheaper boxes. The material resists woodpecker damage, which is a common cause of box failure.
Mounting is straightforward with standard hose clamps and conduit. The box is sized appropriately for the hardware, creating a secure installation that will not spin or tilt. The predator guard offers reasonable protection, though I added a metal ring for extra security in my squirrel-heavy area.
Ventilation and drainage are properly implemented, with gaps that allow airflow without letting in rain. The easy-open design makes seasonal maintenance simple.
This house is ideal for environmentally conscious consumers wanting to support sustainable products. The woodpecker resistance makes it valuable in areas with flicker or sapsucker populations. Those wanting the Audubon brand name at a moderate price will find good value.
The occasional quality control issues mean careful inspection upon arrival is necessary. Shipping times can be inconsistent. Those wanting premium features like viewing windows should consider the JCs Wildlife option instead.
Complete kit includes house pole and protector
Natural cedar wood construction
Steel hole protector prevents damage
Mounting bracket for quick installation
Ventilation at top of nest box
This kit offers convenience for those wanting a one-purchase solution. Getting the house, pole, and hole protector together eliminates the need to source compatible components separately.
The steel pole provides a sturdy mounting option, and the steel hole protector genuinely stops squirrels from enlarging the entrance. When all parts are included and properly assembled, this kit works well for basic bluebird hosting.
The natural cedar construction has the authentic look and smell that many birders prefer. The ventilation at the top helps with heat management, though I would like to see more airflow options for southern climates.
Installation is straightforward with the included mounting bracket, assuming all parts arrive intact. The concept of a complete kit is excellent for beginners who might not know what additional components they need.
This kit is ideal for absolute beginners who want one purchase that includes everything needed to start. The convenience factor is significant if you receive a complete, well-made unit. Those intimidated by sourcing separate components will appreciate the all-in-one approach.
The quality control issues are concerning enough that I recommend checking all components immediately upon arrival. The higher failure rate compared to competitors suggests looking elsewhere if you want reliability. The plastic mounting bracket may not hold up to windy conditions.
After reviewing these 14 options, you might wonder which features truly matter. I have learned through years of bluebird hosting that certain specifications make the difference between success and disappointment.
The entrance hole size is the most important specification for any bluebird house. Eastern Bluebirds require a 1.5-inch diameter hole positioned 6 to 10 inches above the floor. This size excludes European starlings, which need at least 1.6 inches to enter.
Research from Georgia Wildlife shows that oval entrance holes measuring 2 inches tall by 1-3/8 inches wide are even more effective. Bluebirds prefer these 6-to-1 over round holes, and house sparrows tend to avoid them entirely. The Gilwood box design and slot boxes use this oval or slot approach for maximum sparrow resistance.
Never use a bluebird house with a perch below the entrance hole. Perches only help predators and house sparrows gain access. Bluebirds do not need them to enter.
Both cedar and recycled plastic have merits for bluebird housing. Cedar offers natural beauty, insulation, and that wonderful woodsy aroma. It weathers to a silver-gray over time and can last 10-15 years with proper maintenance.
Recycled plastic provides unmatched durability. These houses last 25+ years without fading, cracking, or rotting. They resist carpenter bees and woodpeckers, and require no painting or sealing. The downside is that plastic can get warm in direct sun, requiring thoughtful placement.
The North American Bluebird Society recommends 3/4-inch to 1-inch thick wood for proper insulation. Thinner wood cannot regulate temperature effectively, putting nestlings at risk during extreme weather.
Proper mounting is as important as the house itself. Bluebird houses should be placed on poles 5-10 feet above ground, never on trees where predators can climb. A stovepipe baffle or cone baffle on the pole is essential for raccoon and snake protection.
Face the entrance east or north when possible to avoid direct afternoon sun and prevailing winds. Position the box 100-150 feet from wooded cover, as bluebirds prefer open grassy areas for foraging. Keep boxes at least 100 yards apart to reduce territorial conflicts.
I use half-inch electrical conduit mounted with rebar stakes driven into the ground. This creates a predator-resistant installation that sways slightly in wind, which seems to deter some predators.
Without proper predator guards, your bluebird house becomes a feeding station for raccoons, snakes, and cats. A stovepipe baffle mounted 4 feet above ground on the pole prevents climbing predators from reaching the box.
Entrance hole guards extend the tunnel length, making it harder for predators to reach in and extract nestlings. Metal guards prevent squirrels and woodpeckers from enlarging holes. The combination of a baffle and hole guard provides comprehensive protection.
Some landlords add sparrow spookers after the first bluebird egg is laid. These reflective streamers deter house sparrows while bluebirds are committed to the nest.
House sparrows are the single greatest threat to bluebird nesting success. These invasive birds will kill bluebirds, destroy eggs, and build nests on top of existing bluebird nests. Managing sparrows is non-negotiable for successful bluebird hosting.
The most sparrow-resistant designs are Gilwood boxes with oval holes and slot boxes with narrow horizontal entrances. Standard 1.5-inch round holes will attract sparrows in many areas. Monitor your boxes daily during nesting season and remove sparrow nests immediately.
A Van Ert trap can catch invading sparrows without harming bluebirds. Place it inside the box when sparrows are a problem, and check it frequently. Some landlords also use seed traps to catch sparrows away from nest boxes.
Overheating kills more nestlings than cold in most climates. Proper ventilation through gaps under the roof eaves and drainage holes in the floor are essential. The interior should stay below 100 degrees even on hot days.
Drainage holes prevent nests from flooding during rainstorms. Four 1/4-inch holes in the corners of the floor work well. Some houses include an elevated wire mesh floor that keeps nests above any moisture while also helping with blowfly management.
The best bluebird houses feature untreated cedar or recycled plastic construction, a 1.5-inch entrance hole positioned 6-10 inches above the floor, no perch, proper ventilation gaps, and a hinged side door for monitoring. Top designs include NABS-approved boxes, Peterson boxes for wet climates, and Gilwood boxes with oval entrance holes that deter house sparrows.
Bluebird houses should ideally face east or north to avoid direct afternoon sun and prevailing winds. Position the entrance toward an open grassy area at least 100 feet from dense shrubs or wooded cover. This orientation helps regulate interior temperature and protects the entrance from rain.
Eastern Bluebird houses need a minimum 4x4 inch floor, 12-inch total height, and 1.5-inch diameter entrance hole positioned 6-10 inches above the floor. The interior should be approximately 5 inches deep with rough interior walls or grooves to help fledglings climb out successfully.
Yes, Eastern Bluebirds are cavity nesters and readily use properly designed birdhouses. They do not build their own nests in trees, so nest boxes provide essential nesting sites that have become scarce due to habitat loss and competition from invasive species.
1) Use boxes with oval or slot entrances that sparrows avoid. 2) Install a sparrow spooker with reflective streamers after the first bluebird egg is laid. 3) Monitor daily and remove sparrow nests immediately. 4) Use a Van Ert trap to catch invading sparrows. 5) Never use a box with a perch as perches help sparrows.
Install bluebird houses by late January or early February, before bluebirds begin scouting for nesting sites in early spring. In southern regions, bluebirds may nest as early as March; in northern areas, activity begins in April. Year-round mounting also provides winter roosting sites.
Choosing the best birdhouses for bluebirds comes down to matching the right features to your specific situation. For most backyard birders, I recommend starting with the Kingsyard Recycled Plastic house or the SISTERBIRD 2-pack, depending on whether you value viewing features or quantity.
Remember that the box is just the beginning. Successful bluebird hosting requires proper mounting, predator protection, and commitment to monitoring and managing house sparrows. The reward is watching one of North America's most beautiful songbirds raise their young right in your yard.
I encourage you to start with one box this 2026, learn from the experience, and expand your bluebird trail as you gain confidence. These cavity-nesters need all the help we can give them, and the satisfaction of seeing fledglings emerge from a box you provided is one of the great joys of backyard birding.
