canaria/oscine

The respective influence of testosterone and estradiol on the structure of the Common Canary Serinus canaria song was studied by experimentally controlling blood levels of steroid hormones in males and analyzing the consequent effects on acoustic parameters. A detailed acoustic analysis of the songs

Birdsong is a learned motor behavior controlled by an interconnected structure of neural nuclei. This pathway is bilaterally organized, with anatomically indistinguishable structures in each brain hemisphere. In this work, we present a computational model whose variables are the average activities

Learned communication was a trait observed in a limited number of vertebrates such as humans but also songbirds (i.e., species in the suborder passeri sometimes called oscines). Robust male-biased sex-differences in song development and production have been observed in several songbird species.
