There are three species of bluebird found in North America: Eastern Bluebird; Mountain Bluebird; and Western Bluebird. All three are part of the thrush family. Mountain Bluebirds range in the Rocky Mountains and points west. They prefer open lands, usually over 5,000 feet above sea level.
Male Western Bluebirds are brightly colored in turquoise feathers. Female Western Bluebirds have light blue wing feathers and dull greyish-brown body plumage.
Like other bluebird species, Mountain Bluebirds are cavity nesters and will readily use a nestbox when they are provided. The birds are fairly bold and are usually not disturbed by human activity close to their nesting area.
