It is about nine inches in length. The plumage is a deep slate-color above and lighter below, with a black cap and tail. In habit it is lively, familiar, and unsuspicious. Its call note is a taunting, long-drawn "Kee," a most unpleasant cry; its song is rich, melodious, and often imitative of other birds. During the winter it inhabits the extreme south of the United States, and is found also in Mexico and Central America.
