What’s better to conserve than nature’s beauty the bluebird.

Building bluebird nest boxes is a heartwarming endeavor that fosters a symbiotic relationship between humans and nature. By constructing these small shelters, one becomes a steward of conservation, offering essential nesting sites for Eastern, Western, and Mountain Bluebirds. Beyond the joy of witnessing their vibrant presence, these boxes contribute to the preservation of these iconic species, especially as habitat loss poses challenges. Providing safe spaces for bluebirds to raise their families not only supports biodiversity but also invites a sense of fulfillment, connecting individuals with the beauty of the natural world while actively participating in its safeguarding.

Here are instructions on how to build a basic bluebird nest box, along with guidance on where to place it:

Materials Needed

1. Wood
   • Use untreated, rough-sawn cedar or redwood boards, approximately 3/4 inch (1.9 cm) thick. Avoid pressure-treated wood, as the chemicals can be harmful to birds.
2. Dimensions
   • Follow these general dimensions for a bluebird nest box:
     • Floor Size: 5 x 5 inches (12.7 x 12.7 cm)
     • Height: 9 inches (22.9 cm)
     • Entrance Hole: 1.5 inches (3.8 cm) in diameter, placed about 6 inches (15.2 cm) above the floor
3. Tools
   • Saw, drill with bits, screwdriver, measuring tape, and wood screws.

Instructions

1. Cutting the Wood
   • Cut the boards according to the dimensions specified, creating pieces for the front, back, sides, floor, and roof of the nest box.
2. Assembling the Box
   • Assemble the box by attaching the sides to the front and back with screws. Attach the floor to the bottom. Ensure the box has drainage holes in the floor.
3. Adding the Roof
   • Attach the roof to the box, leaving a slight overhang to provide protection from rain. Ensure that the roof is securely fastened.
4. Creating the Entrance Hole
   • Drill a 1.5-inch (3.8 cm) entrance hole near the top of the front panel. This size is ideal for eastern bluebirds and discourages larger birds from entering.
5. Mounting or Hanging
   • Bluebird nest boxes can be mounted on a post or hung from a wire. If mounting on a post, add a predator guard below the box to deter climbing predators.
6. Location
   • Place the nest box in an open area with a clear flight path to the entrance. Position it facing east or southeast to protect it from prevailing winds.
7. Height
   • Mount the box 4 to 6 feet (1.2 to 1.8 meters) above the ground. This height helps deter predators while providing easy access for bluebirds.
8. Monitoring
   • Check the box regularly, especially during the breeding season, to monitor activity, ensure the box is in good condition, and observe the success of nesting attempts.

Tips

• Avoid Nesting Near Feeders: Position the box away from busy bird feeders to reduce competition and potential conflicts.
• Multiple Nest Boxes: If space allows, consider installing multiple nest boxes spaced at least 100 yards (91 meters) apart. This can reduce territorial disputes and attract more bluebirds.
• Clean the Box Annually: After each breeding season, clean out the nest box to prepare it for the next occupants.

Building and installing a bluebird nest box can contribute to conservation efforts and provide a safe haven for these beautiful birds. Always consider local guidelines and regulations when installing nest boxes.
