About Bluebird Houses

About Bluebird Houses
Bluebirds are separated into three species---eastern, western and mountain. They make their nests in the cavities of scattered trees throughout North and South America. Man-made bluebird houses help house and attract bluebirds.


Natural materials, such as untreated cedar or redwood, should be used for the safety and health of the bluebird.



Mountain bluebirds require an entrance hole of 1 9/16 of an inch, and western and eastern need 1 1/2 inch holes. The eastern's house should be 8 to 12 inches high and 5 inches long by 5 inches wide. The western and mountain birdhouse dimensions should be increased in length and width by half an inch.


Houses should have a back or side door for cleaning, drainage holes in the bottom, a slight roof overhang and vent holes placed on top for proper ventilation.


Birdhouses should be placed on a natural or handmade mount formed from wood or metal in a wide-open rural area. Face it away from prevailing winds, and keep it five feet above the ground.


Common predators include raccoons, squirrels and wild cats. Combat predators by greasing the metal pipe supporting the house or placing a half-inch square hardware cloth around the entrance hole.
