Jook - You can build a Bluebird nesting box and probably lure then into your yard. In general, around 6 inches square, 7 to 8 inches tall, 1 1/4 to 1 3/8 inch hole about 2/3 of the way up, no perch. I use 1 3/8. I hinge the bottom of mine to make it easy to empty in winter, leave it open for about a week to encourage all the bugs to move out, and it's ready for next spring. They have been nesting in them for 4 years straight, a pair set up housekeeping in the first one in a couple of days. It need to be in an open spot with no trees very close, 4 to 7 feet off the ground. Chickadees will fight them for it, I made one with a 1 1/8 inch hole for the Chickadees, Bluebirds can't get in.

That's what mine look like, got a shot of a female about to go out for more groceries. When they have little ones you can tell, it's a nonstop back and forth for both birds.

Finally found the overall view, this is actually the Chickadee box, but the only difference is the size of the entry hole.

I made one for the Tufted Titmouse, it turned out Prothonotary Warblers took it over instead.

Found it...the shot I was looking for, youngster looking around from the box in back, the one with a Male perched on top of it. I;m pretty sure they nest in the same spot year after year, so probably his offspring.
