Western and Mountain Bluebird Birdhouse

Build the western and mountain bluebird nest box with red cedar, pine, or almost any soft wood. Use wood rough-cut on both sides so that birds can grip both interior and exterior surfaces.

Make a 5″ by 5″ floor (inside dimensions) and a 12″ floor to ceiling height (inside front). Drill a 1 9/16″ diameter entrance hole located 10″ above the floor (to top of hole). Cut or drill ventilation openings in the floor and under the roof.

Cedar bluebird house.

Attach a hinged roof for easy access to monitor and clean. Use shutter hooks to secure roof in closed position. Or make a fixed roof and side opening doors. Always use corrosion resistant screws and hardware.

Drill countersunk pilot holes in primary work pieces. Drill regular pilot holes in secondary work pieces. This reduces a tendency for wood to split. It also makes for easy assembly in minutes with a power or hand held screwdriver.

Species specific birdhouse dimensions.

Extend the back wall panel beyond both top and bottom. Drill pilot holes in these long panels for mounting. Drill an extra mounting hole inside the box just under the roof. Stagger these holes so that all are not in line along a single wood grain. Holes in line with grain can weaken and cause wood to split.

Mount bluebird houses 3′ to 6′ high in partial sun and shade on posts in woodland clearings, grove and shelter belt edges bordering fields, among scattered trees, or pasture fence lines. Make a “bluebird trail” of several houses about 100 yards apart; further in wide open expanses and closer in clearings of wooded areas.

In areas where the mountain bluebird range overlaps that of the eastern bluebird, use this nest box which will accommodate all three bluebirds. See mountain bluebirds and western bluebirds species pages for more habitat and mounting instructions.

Monitor the boxes for unwanted squatters. Deter predators with steel posts or sheet metal wrapped around wood posts. Avoid shade, but also avoid prolonged direct sunlight through the entrance if possible.

Tree swallow nest boxes placed between bluebird nest boxes invite good neighbors that will help defend against sparrows, but these bird houses also invite sparrows, so monitor the swallow houses as well as the bluebird houses.

Remove and clean the box well after the brood rearing season is past. Store clean and dry.

Chickadees, nuthatches, titmice, wrens, tree and violet green swallows (and sparrows!) may use this nest box.
