In hot climates, face them to the north or east to avoid direct midday sun. The most important aspect of mounting is to face the box toward some tree or shrub within 100 feet. When the young leave the nest they will make an initial flight to safety. Whatever you do, make sure you place your nest boxes in good bluebird habitat. Not even the best bluebird house will attract bluebirds if it is in the wrong place.
Bluebirds nest primarily in suburban and rural areas.
During breeding, bluebirds hunt insects by scanning the ground from a perch, spotting an insect, then swooping down to the ground to get it. Scattered young trees or shrubs, fence posts and lower branches of a lone mature tree make good hunting perches. Sparse or low vegetation is also important since it enables the bluebirds to see and capture insects. Cut meadows, mowed lawns and grazed fields are good. Good areas for bluebird nest boxes include open fields, fence rows, orchards where no pesticides are used, cemeteries, large lawns, golf courses, public parks, along open highways that are kept mowed and pastures.
