The Mountain Bluebird is a slightly smaller bird than a Robin. It has a large round head with a stocky body. The small, pointed bill is black. The legs and feet are also black.

The male is a deep sky blue on its upperparts, wings and tail. The chest is blue fading to light blue and then white on the belly.

The female is gray with a gray throat, back and crown. There is some some blue on her wings.


The Mountain Bluebird can be found in open areas such as meadows and agricultural areas. They also like the edge of the forest where it meets the prairie. They prefer a habitat with scattered trees and shrubs.


In winter the Mountain Bluebird can be found from Oregon and Colorado south to Central Mexico.

The Mountain Bluebird breeds from New Mexico and Arizona in the south through western Canada to central Alaska in the north and from areas in northern California in the west and as far east as Colorado.


The Mountain Bluebird eats insects and small fruits. It will watch for insects from a perch or while flying close to the ground. It will often catch its prey by dropping to the ground or even catching it in flight. In the winter they forage for insects and also feed on berries.


Mountain Bluebirds are cavity nesters. The male will select a nesting site in a natural cavity in a tree or even in rocks. It may also choose an abandoned woodpecker hole. The male will then try to attract a female by calling and flying in and out of the selected site.

Once the pair has mated, the female builds the nest. The nest is made from grass. It is lined with fine grass, soft bark, hair, or feathers. The male stays busy by guarding the site.

The clutch contains 4 to 7 eggs and the incubation period is about 13 days.

Mountain Bluebirds often choose nest boxes or bird houses for their nesting sites.

A Few Things You Probably Didn't Know About the Idaho State Bird:
