Western meadowlark
The western meadowlark is the state bird of six states: Montana, Kansas, Nebraska, North Dakota, Oregon, and Wyoming. The northern cardinal, which represents seven states, is the only bird to hold the status of state bird in more states.
Carolina wren
In 1930, the South Carolina Federated Women's club adopted the Carolina wren as the unofficial state bird over the eastern mourning dove and pushed for its official state adoption until 1939, when the South Carolina Legislature named the northern mockingbird as the state bird. In 1948, the legislature repealed their previous decision, and the wren became the official state bird.
