These birds live as far north as Maine or Nova Scotia, Canada down south through Florida and the Gulf Coast. They range as far west as South Dakota, Nebraska and Texas. They have also been introduced to California, Hawaii and Bermuda. Northern cardinals do not migrate so they live in the same place year-round.
Cardinals are monogamous birds whose relationships with their spouses are harmonious, romantic and musical. The male and female sing duets, calling similar songs to each other. Native American lore says if a cardinal crosses your path or attracts your attention, and you're single, there may be a romantic relationship in your near future. If you're already in a relationship, you may experience renewed romance and courtship.
