The other day, I noticed two pairs of bluebirds squabbling over the house on the pink post in my backyard. Wanting to give them another option, I decided to add another bluebird house—this time on a blue post.
I purchased an inexpensive bluebird house from Amazon and customized it by reinforcing the entry hole to deter predators. Squirrels had already started gnawing at the opening, and snakes are always a concern, as they prey on eggs and nestlings. If you’re looking to attract bluebirds to your yard, now is the perfect time—bluebird nesting season is just beginning in Florida and will soon be underway in more northern regions.
Choosing the Right Bluebird House
A proper bluebird house should have:
A hole size of 1.5 inches in diameter (to prevent larger birds from taking over)
No perch, as perches can attract unwanted predators
Proper ventilation and drainage to keep the nest dry
Easy access for seasonal cleaning
Where to Place Your Bluebird House
To increase the chances of attracting bluebirds, place the house:
4 to 6 feet high on a post or pole (not on a tree, which makes it easier for predators to reach)
In an open area with short grass, away from dense trees or shrubs
At least 100 yards apart from another bluebird house, as they are territorial
Facing east or southeast, if possible, for morning sun and warmth
Protecting Bluebirds from Predators
Keeping bluebirds safe is key to a successful nesting season. Here are some predator deterrents:
Install a metal hole guard to prevent squirrels from enlarging the entrance
Use a predator guard (baffle) on the pole to keep snakes and raccoons from climbing up
Monitor for invasive species like house sparrows, which aggressively take over bluebird nests
Maintaining the Birdhouse
Bluebirds are more likely to return if their house is well-maintained. Be sure to:
Check for damage before nesting season begins
Clean out old nests after each brood to encourage new ones
Monitor activity to ensure bluebirds, not invasive birds, are using the house
