The state bird of Iowa is the American Goldfinch. It officially became the state bird in 1933. Yet it is not the most commonly seen bird in Iowa, and before you ask, no it's not hawks either.
One of the things I enjoy in the Fall & Winter time is feeding the outside wild life. A lot of people like myself enjoy feeding the birds, but are not to keen on feeding the squirrels. Hey, the squirrels got to eat too.
