Boxes can be installed in pairs about 18 to 20 feet apart or one by itself. These pairs or boxes should then be about 100 yards apart. Bluebirds are territorial so two different couples will not use boxes placed too close together.
In open grass lands away from woods/brush, houses, barns, tool-sheds and where there is short (chemical free) grass. A clean source of water is also necessary.

Bluebirds eat insects when available and fruits and berries during colder months.
