There are three species of these colorful North American birds. Eastern and western bluebirds have a reddish brown breast.They are much admired for their lovely coloring and for a distinctive song that many hear as "chur-lee, chur-lee."The mountain bluebird also inhabits much of western North America—often at elevations above 7,000 feet (2,133 meters).Bluebirds eat small fruits and hunt insects, spiders, and other creatures from above. Females lay four or five eggs and incubate them for about two weeks. Young remain in the nest, cared for by both parents, for an additional 15 to 20 days. Bluebirds often have two broods in a season. Sometimes, a young bluebird from the first brood will remain in the nest and assist its parents in caring for the second.
Bluebirds living in higher latitudes may head south if food becomes scarce or temperatures too cold
