Distribution and habitat

The Mountain Bluebird is migratory. Their range varies from Mexico in the winter to as far north as Alaska, throughout the western U.S. and Canada. Northern birds migrate to the southern parts of the range; southern birds are often permanent residents. Some birds may move to lower elevations in winter.

Feeding

These birds hover over the ground and fly down to catch insects, also flying from a perch to catch them. They mainly eat insects and berries. They may forage in flocks in winter, when they mainly eat grasshoppers.

Breeding

Their breeding habitat is open country across western North America, including mountain areas, as far north as Alaska. They nest in pre-existing cavities or in nest boxes. In remote areas, these birds are less affected by competition for natural nesting locations than other bluebirds. Females usually build the nests themselves.

It is the state bird of Idaho and Nevada.
