Woodlink Bluebird House Model BB1 — Cedar Nest Box, 1.5" Entrance, Ready-to-Mount

The Woodlink Wooden Bluebird House Model BB1 is a fully assembled, cedar nest box built to the correct proportions to attract Eastern, Western, and Mountain Bluebirds.

Made from reforested, kiln-dried inland red cedar and fastened with rust-resistant zinc chromate screws, this bluebird house combines weather resistance with a blueprint based on bird-habitat research. The BB1’s 1-1/2" entrance, 5" x 5" floor and 6" mounting height above the floor mirror the dimensions that bluebirds prefer, while integrated ventilation and drainage help keep nests dry and comfortable. It ships ready to mount and opens easily for monitoring and cleaning.

How does this house encourage bluebirds to nest?

The BB1’s dimensions—entrance size, floor area and internal height—match what bluebirds seek for nesting. The 1-1/2" (1.5") hole deters larger competitors while remaining inviting for bluebirds. Natural cedar helps regulate internal temperature and reduces insect pressure compared with some untreated woods.

• 1-1/2" entrance centered 6" above the floor to match bluebird preferences
• 5" x 5" floor provides appropriate nest footprint
• Natural cedar resists rot and insects
• Entrance discourages house sparrows and starlings

What features make maintenance and monitoring simple?

The front panel slides down to give full access to the nest without dismantling the box, so you can check progress and remove old nesting material quickly. A drain hole in the floor and a top ventilation gap keep the interior drier, reducing the need for frequent interventions. All fasteners are rust-resistant so the box remains serviceable season after season.

• Easy open sliding front for quick nest checks and cleaning
• Drain hole at base prevents water pooling
• 1/2" ventilation gap near the top improves airflow
• Rust-resistant zinc chromate screws for longevity

Where and how should I mount the BB1 for best results?

Mount the BB1 on a pole or post in an open area with scattered perches nearby—bluebirds favor open fields, edges, and yards with low vegetation. Position the entrance 4–6 feet above ground for optimal visibility and predator avoidance; mounting higher can also be effective depending on local conditions. Avoid placing it close to dense shrubs or thick branches that provide cover for predators.

• Mount on pole/post in open habitat with nearby perches
• Entrance recommended 4–6 feet above ground, adjustable to local needs
• Keep clear of dense shrubbery and predator cover
• Fully assembled box simplifies installation

Who is this for? The Woodlink BB1 suits homeowners, bird enthusiasts, land managers and conservation volunteers who want an effective, low-maintenance bluebird nest box built to species-appropriate dimensions. If you want a ready-to-install cedar box that balances durability, ventilation and predator deterrence—while making monitoring and cleaning straightforward—this model is a practical choice. It’s also a good option for schools or community projects that need a reliable, American-made nesting box for bluebird restoration efforts.
