“What is the best bluebird house placement to attract bluebirds to nest in my backyard?”
Place nest boxes in the sunniest, most open area possible, away from your house or deep shade. Bluebirds prefer large expanses of short grass with a clear flight path, ideally facing a field. Try not to place the house too close to feeders. Make sure it is mounted 5 to 10 feet off the ground. Bluebirds do not tolerate swaying birdhouses, so anchor the nest box firmly to a smooth round pipe.
“Our bluebird house had eggs and babies for many years. One year there were four eggs to start, then three were gone and the fourth had been opened. What happened?”
House Wrens in Bluebird House
This sounds like the work of a house wren. While small and cute, house wrens can be hostile during nesting season. If they set up house in your yard and encounter other cavity nesters they deem too close for comfort, they’ll pierce the eggs of other species and carry them off. So we have to learn to love them in spite of their behavior. The best way to protect your bluebirds is to make sure the nest box is a fair distance away from the dense cover preferred by house wrens, and to install another box a good distance away from your existing box.
