Nest boxes for bluebirds should be made of untreated wood, and they should have a 1.5-inch entrance hole. The inside of the box should be about 6 inches square and 8 inches deep. The box should also have a drainage hole in the bottom, and it should be mounted 5-10 feet off the ground in a tree or on a post.
In addition to providing nest boxes, people can also help bluebirds by planting native plants that attract insects, which are a food source for bluebirds. Bluebirds also appreciate sources of water, such as bird baths. By providing these resources, people can help bluebirds to thrive and successfully raise their young.
Here are some additional tips for helping bluebirds with nesting:
* Place the nest box in a quiet, sheltered area away from predators.
* Avoid placing the nest box in direct sunlight, as this can cause the eggs to overheat.
* Clean the nest box regularly to remove any debris or parasites.
* Monitor the nest box for signs of predators or other problems.
* If you find a bluebird nest that has been abandoned, you can try to relocate it to a safer location.
By following these tips, you can help bluebirds to successfully raise their young and contribute to the conservation of this beautiful species.
