We’ve always found that having a nest box open and ready in the early season is a great way to attract bluebirds. Many times we are able to get one nesting early in the season before some of the more aggressive birds (such as the house sparrow and the house wren) arrive to compete for the nest boxes.
We’ve attached the nest boxes on hedge posts and metal T-posts (used for fencing), but you could also a commercial wooden post. You can mount them right on trees, but they seem to be more susceptible to predators. (Raccoons, snakes and other climbing predators can easily climb the tree and destroy the nesting birds. Squirrels have also been know to chew and destroy the box itself!)
Once the boxes are out, you are ready for business! Now all you need is spring and the return of the bluebirds. But I’ll have to admit, that seems pretty far away right now! As I am writing this, we are under yet another Winter Storm Warning, and March is just 2 weeks away!
But the thought of spring with all the green leaves, warmer weather and the bluebirds nesting is enough to give me hope that sooner or later, even this winter will have to end! Preparing the bluebird nest boxes is just another act of faith, just like buying my garden seeds!
