Spectrogram of river otters calling and splashing at Canyonlands National Park, Utah. 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. The audio clip above is extracted from between 109 - 120 seconds. Look for a cluster of bright vertical lines around the 114 second mark.
