Bluebird. A small bird of the thrush family Sialia sialis, very common in the United States. The upper part of the body is blue, and the throat and breast of a dirty red. It makes its nest in the hole of a tree or in the box that is so commonly provided for its use by the friendly farmer. The bluebird is the harbinger of spring to the Americans; its song is cheerful, continuing with little interruption from March to October, but is most frequently heard in the serene days of the spring. It is also called blue robin or blue redbreast, and is regarded with the same sort of sentiments as the robin of Europe.
