      Compare the range of the eastern bluebird to the very similar looking western bluebird. The eastern bluebird dominates the eastern half of the United States from the southern tip of Texas up through North Dakota and into southern Manitoba and Saskatchewan. The western bluebird is concentrated in the western coastal states.
