I just moved my Christmas-present birdhouse realizing I had forgotten and put it on a tree that is too close to the air conditioner and its noise, and it may have been too close to the window with its lights and motion as people and cats move around.
I put it on a tree across from the front of the house, slightly higher. I'd be surprised if we get a nest this year, though some birds do nest for a second brood, i think. We'll see what happens. The birds definitely inspected it before the a.c. came on regularly.
By the way, bluejays are in the Corvid family, like crows and ravines. That surprised me when I learned it.
