Song: Song is a rapidly ascending series of buzzy whistled, sometimes more slowly with the initial notes distinctly separated from one another "zu-zu-zee-zeezeezeezeeeeee" and on other occasions is a very rapid "zeezeezeezeeeeeeeeeee". Field Sparrow song similar in pattern, but notes clearer and the delivery like a bouncing ping pong ball.
