Zebra Finch song.

Most of the data I use is recorded from the neurons in Zebra finch, an Australian song bird often used as a model animal for learning. The particular value of using song bird in studying primary processing of sensory information is that a corpus of songs from the same species is considered a good proxy for the natural acoustic environment. It is important to use natural stimuli, neuronal processing is likely to be tuned to natural stimuli and processing is likely to exploit the statistical structure of the environment. However, what is meant by natural is hard to define, we get away with not thinking about this by pretending a collection of bird songs will do, this isn’t proved, but it is plausible.

Anyway, above is a recording of a Zebra finch singing, first a series of squawks, announcing the song, then the song itself.
