Influence of social conditions in song sharing in the adult canary.

Résumé

In songbirds, experience of social and environmental cues during a discrete period after birth may dramatically influence song learning. In the canary, the ability to learn new songs is assumed to persist throughout life. The aim of the present study was to investigate whether social context could guide changes in adult song. Three groups of canaries were kept in different social and temporal conditions. Results showed that the multiple hierarchical levels of the canary song structure were affected by social environment: songs of males housed together for 2 years were more similar than those of males that spent the same time in individual cages in regard to acoustic parameters, syllable repertoire and repertoire of sequences of two-syllable types. However, social housing did not result in the emergence of a group-specific vocal signature within songs. In conclusion, these results suggested that under the influence of social factors, a copying process could allow adult canaries to adjust, at least in part, their songs to those of other individuals.
