There exists in the central United States, from South Dakota and Illinois to Texas and Mexico, a bird which has interested students in that region to no small extent. It has been interesting not because of any phenomenal habits or any beautiful color, but because of its modesty of dress and its elusive habits. Although common in its range it seems to have been little studied by the bird student.
