State Bird of Illinois, Indiana, Kentucky, North Carolina, Ohio, Virginia, and West Virginia

Such is the Cardinal's claim to fame.  

Originally, a songbird found almost exclusively in the Southeast, the cardinal has expanded its range due to an increase in food supply in northern climes, as far north as Canada.  Such increases in food supply are reputed to be generated by suburban homeowners and an epidemic of winter birdfeeding.   Regardless of where it finds its food, in the South or the North, in the feeder or in the wild, Cardinals do not migrate.    

Instead, the brightly colored mail birds will expend their energy aggressively defending their territory.   Like people, that aggression can go a wee bit too far, as cardinals have a habit of running headlong into windows, believing their own reflection to be an intruding male.   The most aggressive (or stupid) of these birds will repeat the behavior often enough to commit suicide (a la window) in relentless pursuit of a non-existent competitor.  

 See any parallels to human behavior?
