Providing a well-designed nest box is one of the best ways to support bluebirds in your area. Bluebirds rely on suitable nesting sites to raise their young, and with the right materials and design, you can help them thrive. Here’s what you need to know about creating an ideal bluebird nest box and how Exotic Nutrition products like the Sturdy Nest Box, Live Mealworms, Mealworm & Sunflower Pie, and Dried Mealworms can help attract these beautiful birds.
Choosing the Right Materials
When selecting materials for a bluebird nest box, durability and safety are key.
-
Recommended materials: 3/4-inch wooden boards (such as cedar or redwood) or PVC pipe with attachable wooden roofs.
-
Avoid: Pressure-treated wood, as it contains toxic compounds that can harm birds.
-
Not suitable: Paper milk cartons or corrugated cardboard, as they lack durability and protection.
Entry Hole Size and Floor Dimensions
Different species of bluebirds require specific entry hole sizes:
-
Eastern Bluebirds: 1-1/2 inch round holes, 1-3/8 x 2-1/4 inch vertical oval holes, or 1-1/8 inch horizontal slots.
-
Western and Mountain Bluebirds: 1-9/16 inch round openings.
-
Floor sizes: Eastern Bluebirds need approximately 4x4 inches, while Western and Mountain Bluebirds require at least 5x5 inches to accommodate their larger clutch sizes.
Essential Features for Bluebird Nest Boxes
-
Easy Access for Monitoring & Cleaning:
-
The box should open easily from the top, side, or front to allow monitoring and cleaning.
-
A secure latch prevents access by predators.
-
-
Proper Ventilation & Drainage:
-
Drainage holes in the bottom help keep nesting materials dry.
-
Ventilation openings near the roof promote airflow while preventing overheating.
-
-
Predator Protection:
-
A 5-inch roof overhang above the entrance can help deter raccoons and cats.
-
Avoid wooden guards over the entry hole, as they do not effectively stop predators.
-
Mounting boxes on greased pipes or waxed metal conduits can prevent climbing predators from accessing the nest.
-
-
Mounting Considerations:
-
Securely mount the box on a post such as water pipe or electrical conduit.
-
Avoid mounting boxes less than 5 feet from the ground to reduce predator access.
-
-
No Perches:
-
Bluebirds do not need perches, and including them may attract aggressive non-native species like House Sparrows.
-
-
Interior Surface Design:
-
A rough-textured inner front wall below the entrance hole helps chicks climb out when they are ready to fledge.
-
