where it lives
Preferring open rangeland or fields, this thrush often catches insects on the fly. At rest, it typically sits on fence posts or treetops. Unlike other thrushes, these nest in tree cavities, preferring aspens, but also readily nests in boxes. To this end, the Lillooet Naturalist Society manages about 150 nesting boxes for these beautiful birds.
Mountain bluebirds have been affected by fire suppression, which allows forests to grow in on grasslands. The invasive European Starling also competes with them for nesting sites. While population numbers are going down, presently, they are not threatened or at risk.
