  The rapid, melodious chriping of an alder flycatcher.

Spectrogram of an alder flycatcher. Spectrograms are graphs that visualize sounds. The brightness of the colors shows sounds’ amplitude (loudness) across different frequencies (pitches), shown from bottom to top, and over time, from left to right. This spectrogram visualizes the flycatcher's high, variably-pitched song.
