[PDF] Dynamics behind rough sounds in the song of the Pitangus sulphuratus. | Semantic Scholar

The examples discussed in this Review, integrating biological experiments and biomechanical modeling using non-linear dynamical systems, illustrate how a morphological adaptation can produce complex acoustic properties without the need for complex neuromuscular control.

This work employs a dynamical systems model for song production in suboscine birds in order to translate the vocal muscles activity during sleep into synthetic songs, and argues that this approach poses the biomechanics as a unique window into the avian brain, with biophysical models as its probe.
