Abstract

A description of the general principles underlying Zebra Finch song is given in standardized terminology. Differences were looked for in songs produced in two different contexts: courtship song and undirected song. In more than 7 males (domesticated and wild ones), clear differences were found with respect to number of introductory elements, number of motifs, speed of performance, and rigidity in sequence, indicating two distinct song types. Motivational problems and the adaptive value are discussed.
