This Backyard Wood Birdhouse is perfect for bluebirds, wrens, and other cavity nesting birds. Comes with the Hawk Eye cam already installed so all you have to do is hang the box and run the cable to your television or computer and start enjoying.  Made of eastern White Pine with a slate guard which keeps squirrels and other birds from enlarging the entrance hole. With a 4" x 4" floor it will welcome many small birds.
