There are three species of these colourful North American birds. Eastern and western bluebirds have a reddish brown breast, which contrasts with their predominately blue plumage. Their relative, the (male) mountain bluebird is entirely blue.
Eastern bluebirds are primarily found east of the Rockies, and range from Canada to Mexico and Honduras. They are much admired for their lovely colouring and for a distinctive song that many hear as "chur-lee, chur-lee." The eastern bluebird is the state bird of both New York and Missouri.
