Missouri State Bird
Eastern Bluebird (common name)
Sialia sialis (scientific name)
The eastern bluebird is a small blue thrush with a soft, pleasant warbling song. It was designated the state bird of Missouri in 1927, and New York followed suit in 1970. Bluebird populations fell precipitously in the early 20th century because of competition from starlings and sparrows for nest holes. The male bluebird has blue wings and tail and a reddish-orange chest. The female is grayer with a lighter orange chest. Both males and females have a stocky body, a round head, and a short black bill. Their diet consists of insects in spring and summer fruit and berries in fall and winter.
