Amplitude modulation of sexy phrases is salient for song attractiveness in female canaries (Serinus canaria)
The salience of a short conspecific song phrase versus a long one or a short heterospecific song phrase was tested in females of the common domesticated canary (Serinus canaria). All phrases were computer-edited. The copulation solicitation displays (CSD) served as an index of female responses. The results support the hypothesis that female canaries are able at the onset of a song phrase stimulus: 1) to respond to a conspecific one by displaying high levels of CSD and 2) to discriminate a conspecific from a heterospecific one. Proximal explanations examine the link between perceptual processes and phonology in the canary. Functional explanations investigate the relations between female responsiveness and the process of pair formation.
