The Mountain Bluebird was once called the Arctic or Ultramarine Blue-Bird — names that recognize its northerly range and the male’s vivid sky-blue plumage. This small thrush, about two-thirds the size of an American Robin, is the state bird of Idaho and Nevada.
Mountain Bluebirds breed in high, open country across western North America, as far north as Alaska. Usually nesting at elevations above 7,000 feet, they favor open territories year-round, including alpine meadows and clearings, as well as lower-elevation grasslands, plains, fields, farmland, pastures, and gardens.
