In this work we revisit the path that has been travelled during the last years towards the modelling ofthe avian vocal orgal, the syrinx, using numerical and theoretical techniques from bifurcation theoryas analyzing tools and presenting experimental support for the models. This fruitful perspectiveallowed retracing many acoustic features of syllables to intrinsic properties of the syrinx, therebyrelocating the bird?s phonatory organ from the role of a mere vocal instrument of the nervous systemto a central source of complex acoustical behavior.
