Abstract
Bird songs make an attractive model for studying complex systems. They may range from simple repeated sequences, to complex sequences of different phrase types, much like human language. There is probably no single way to best characterize their complexity. We should avoid saying that that “bird songs are in complexity class X”. The diversity of examples suggests that the song of one bird species or another can probably be found to exemplify and model many kinds of complex systems. We suggest that the complexity classes for cellular automata distinguished by Wolfram might give some insight into the capacity of bird songs to transmit information and of the complexity needed to generate them.
