Figure 6.2

Upper panel: A sound spectrogram analysis of a typical song of a white-crowned sparrow is shown (frequency on the vertical axis versus time in milliseconds on the horizontal axis). The smallest elements, the notes, are combined to form syllables (lowercase letters), and these are repeated to form phrases. White-crowned sparrow songs typically begin with (a) a long whistle followed by (b, c) trills and (d) buzzes. (From Doupe and Kuhl, 1999.) Lower panel: A spectrogram of a series of ultrasonic vocalizations from a male mouse (frequency versus time in seconds). Although the individual syllables are not reproduced as precisely as in the bird, it is possible to recognize and quantify them. (From Collin Yu and Natalia Malkova)
