Gilbertson Bluebird Nest Box – NABS Approved
$35.99
Unit price perWhen it comes to bluebird nesting, design matters more than decoration. The Gilbertson Bluebird Nest Box is one of the most proven nest box designs ever created — trusted by bluebird conservationists for decades and NABS Approved for proper nesting success.
This nest box follows the original Gilbertson design, offering the right interior space, ventilation, and drainage bluebirds need to feel safe and raise healthy broods. Its simple layout encourages faster nesting while making monitoring and seasonal cleaning easy for you.
Choose between a natural cedar roof for a classic look or a poly lumber roof for maximum weather resistance and zero maintenance. Both options are built to handle years of outdoor exposure.
Whether you’re starting a bluebird trail or adding a trusted box to your backyard, this is a proven, no-nonsense nest box built to support bluebirds — season after season.
Cavity Size: 4" x 7.25"
Entrance Hole 1.5" diameter
To attach or remove the PVC cavity from the roof squeeze the sides towards the top edge, this will allow it to slide on and off the protruding screws on the bottom of the roof.
To mount your bluebird house, you have two easy options:
Option 1: Use a 7-foot long, 1/2-inch metal electrical conduit (available at most hardware stores). Simply push or drive it into the ground about 18–24 inches deep so it's stable, then attach the house near the top.
Option 2: Use a 36-inch ground stake and slide a 5-foot long 1/2-inch conduit over it. This makes setup easy and adds extra support.
Both methods give your bluebird house the right height and stability for a safe nesting space.

Eco-Friendly & Durable
