What Is Idaho’s State Bird? How Was It Decided?

Last Updated on

Mountain Bluebird

Idaho’s state bird is the brilliant and vibrant mountain bluebird (Sialia currucoides), a small migratory thrush that calls the mountains of western North America its home. Mountain bluebirds can usually be found in habitats such as prairie, alpine tundra, sagebrush steppe, and open country with few trees where they forage in pastures. When foraging, mountain bluebirds have been observed to hover and pounce on their insect prey from elevated perches.

This omnivorous bird feeds on small fruits and insects such as grasshoppers, flies, and spiders and is lanky and long compared to other bluebirds. Mountain bluebirds can also be found in large flocks feasting on delicacies such as juniper berries in the colder months. Male mountain bluebirds are a stunning turquoise blue in color with a paler chest and white feathers under the tail. Females, however, are dimmer with a gray-brown coloration and touches of pale blue on the wings and tail.

How Was Idaho’s State Bird Decided?

Idaho chose the mountain bluebird as its state bird on February 28th, 1931 after school children in the state suggested it. When the Idaho General Assembly officially adopted the mountain bluebird through legislation, they pointed out its connotations of hope, happiness, and love. The mountain bluebird is also the state bird of Nevada.
