Joeyk210 ~ Robins are popular birds. Three states claim them as their State Bird...Michigan, Connecticut & Wisconsin!
I guess if a state treasures a bird it doesn't matter how many other states claim the same bird. I live in Illinois where the State Bird is a Northern Cardinal. The Cardinal is State Bird of Seven different States...Illinois, Indiana, Kentucky, North Carolina, Ohio, West Virginia & Virginia!
I came across this website that shows all of the state birds. You can also click the link for each bird to find out more about them.
