As early as the end of February and as late as June, the male bluebird will locate a nesting site, establishes a territory around it of two to five acres, and sings to attract a female and warn other male bluebirds to stay away.
The nesting box - well, the location says it all. Select an open area with scattered trees and sparse ground cover. Avoid underbrush, tall grass, dense woods, farm buildings, and areas where pesticides are used. The nest box should be placed on a pole (not a tree) about five feet high, facing the entrance hole east to south.
Last year, the bluebird house in the garden didn't have any tenants. The one in the front yard had one and then they left after the eggs were destroyed by another bird.
I need to move the bluebird houses to another spot. You would think that'd be pretty simple but it's not - there's bushes, trees, barns - all kinds of stuff get in the way.
