About This Species

Scan open meadows, grassland, and high-elevation clearings across the western mountains for this bluebird hovering low over grass before dropping onto insects, a hunting style distinct from the perch-and-pounce habit of other bluebirds. Males show a vivid sky-blue overall, unmistakable in good light. Breeding season in alpine and subalpine meadows offers the best views, while birds move to lower, more open country in winter.

Ethical Viewing Guidelines

  • Watch from a distance, especially near nest boxes or natural cavities, since flushing a brooding female can chill eggs or young in the cool, high-elevation habitats this species favors.
  • It is protected under the Migratory Bird Treaty Act across its US and Canadian range.
  • If checking a nest box, do so briefly and only when necessary, and avoid repeated visits during incubation.
