This male Spotted (Rufous-Sided) Towhee (Pipilo maculatus) was sitting in a tree in Sedona, Arizona. He let me sit 6 feet from him while he sang these two variations. The first notes are a jay-like call, or mew, which he repeated for several minutes,then he started the second, which is a fantastic short song. The spectrogram shows his frequencies to exceed 11 KHz!
