Three audio spectrograms of a Bewick's wren recorded within a minute. The visual representation makes recognizing the bird easier than the sound, at least to me. Notice that the distinctive chirps come as a set of three, four, and five. The bird either can't count or it can count and changes this feature of it's call for reasons a mere mammal can't understand.

Recorded on a home-brew Birdnet-Pi in my back yard in San Diego.
