Is Morphometry an Indicator of the Number of Sexy Syllables in the Song of Yellow-Fronted Canary (<i>Serinus mozambicus</i>)?

Birds use song for several goals as defending territory, alerting a partner to the presence of a predator, or wooing a female for breeding. This study aims to identify the morphometric parameters which determine the variability of the number of syllables in the “sexy” songs of yellow-fronted canary....
