Stan’s Notes: Common in open mountainous country, this bird nests throughout Utah. Due to conservation of suitable nest sites (dead trees with cavities and man-made nest boxes), populations have increased dramatically over the last 50 years. Like other bluebirds, Mountain Bluebirds take well to nest boxes and tolerate close contact with humans. Young will imprint on their first nest box or cavity, then choose a similar type of box or cavity throughout the rest of life.
