Mountain Bluebirds are found in the western parts of Canada and
the United States. They are found at elevations above 5,000 feet,
and they nest in open areas such as meadows, hayfields, grain
fields, savannas, prairies, clear cuts, and the edges of
coniferous and deciduous forests. The beginning of the breeding
season varies with latitude; birds in the southern portion of the
range begin in early April, birds in northern latitudes begin in
late May. Mountain Bluebirds reuse old nest sites both within a
breeding season and in successive breeding seasons. Pairs that
successfully raise a brood in a nest box may become faithful to
that particular type of nest box. First-year breeding birds tend
to nest in boxes identical to their natal box.
Mount the Mountain Bluebird House so the entrance hole is
approximately five feet above the ground. If possible, face the
house away from prevailing winds and facing towards a tree or
shrub which is within 100 feet of the house. Trees and shrubs
provide a landing spot for the young bluebirds when they first
leave the house. This will keep them off the ground, away from
predators. Mountain Bluebird Houses should be spaced at least 300
yards apart.

|  Mountain Bluebird Range MapUnlike other bluebird species, male Mountain Bluebirds have no chestnut red on their bodies. The head, back, wings, and tail are a bright sky blue. Males are light blue from the chin to the belly, and grayish-white on the belly and undertail coverts.
Females have brownish gray upperparts. The wings, rump, and tail are a pale or light blue. Females sometimes have a pale reddish throat and breast, but more commonly, the throat and breast are gray brown.
Juveniles look like adult females, but they are darker and less colorful. Their breasts and sides are streaked with brown.
