What city can you find blue cardinals?

Blue cardinals, specifically the blue variant known as the Eastern Bluebird, can be found in various cities across the eastern United States. However, if you are referring to blue-colored birds resembling cardinals, it's important to note that blue cardinals do not exist; cardinals are typically red. If you mean the presence of bluebirds, cities like Richmond, Virginia, or Nashville, Tennessee, can be good places to spot them in suitable habitats.
