SISTERBIRD Cedar Bluebird Houses 2-Pack — 1.5" Entrance, Copper Predator Guard, Easy-Clean Front

These are two untreated cedar bluebird houses with 1-1/2" entrance holes, interior grooves, and copper predator guards designed to attract and protect small songbirds while being easy to assemble and clean.

Bring nesting habitat to your yard with a pair of SISTERBIRD bluebird houses built from weather-resistant cedar and thoughtfully detailed for bluebirds, tree swallows, wrens, and chickadees. Each kit arrives as unfinished wood so you can personalize it, and includes features that discourage starlings and other unwanted intruders while making life easier for fledglings and homeowners.

How do these houses attract the right birds?

The entrance hole measures 1-1/2 inches, a size known to welcome desirable small songbirds while being less attractive to larger, invasive species. The natural cedar finish and rough interior surfaces give birds secure footing during landings and departures.

• 1-1/2" entrance hole tuned for bluebirds, wrens, tree swallows, and chickadees
• Untreated cedar provides a natural, breathable shelter
• Rough interior surfaces help birds climb in and out

Why is cedar a good choice for an outdoor birdhouse?

Cedar resists rot and stands up to moisture and sun better than many softwoods, offering a longer-lasting nest box without chemical treatments. The wood weathers gracefully and can be painted or decorated if you want a custom look for your yard.

• Untreated cedar minimizes chemicals near nests
• Durable against weather and seasonal changes
• Simple to paint or leave natural for a rustic aesthetic

What safety features protect chicks and discourage predators?

Each SISTERBIRD house includes a copper predator guard around the entrance to reduce pecking and predator access, and interior grooves act like a tiny ladder so fledglings can climb out when it’s time to leave the nest. The entrance sizing further limits access to larger, unwanted species.

• Copper predator guard installed around the entrance hole
• Interior grooved surface helps fledglings exit independently
• Appropriate entrance diameter reduces unwanted occupants

How easy is assembly, cleaning, and seasonal reuse?

The houses are designed for simple assembly with basic tools so families can build and customize them together. A front panel opens for quick cleaning after nesting season, letting you refresh the box for reuse year after year.

• Simple screwdriver assembly; great for family projects
• Front-opening panel allows thorough cleaning between seasons
• Reusable design makes this a sustainable yard investment

Who is this for? These SISTERBIRD 2-pack bluebird houses suit backyard stewards, educators, and gift-givers who want to support native songbirds with a durable, customizable nesting solution. They’re ideal for homeowners, gardeners, schools, and anyone looking for an engaging DIY project that benefits wildlife and adds character to outdoor spaces.
