Although song development in songbirds has been much studied as an
analogue of language development in humans, the development of vocal
interaction rules has been relatively neglected in both groups. Duetting
avian species provide an ideal model to address the acquisition of
interaction rules as duet structure involves time and pattern-specific
relationships among the vocalizations from different individuals. In this
study, we address the development of the most striking properties of
duets: the specific answering rules that individuals use to link their own
phrase types to those of their partners (duet codes) and precise temporal
coordination. By performing two removal experiments in canebrake wrens
(Cantorchilus zeledoni), we show that individuals use a fixed phrase
repertoire to create new phrase pairings when they acquire a new partner.
Furthermore, immediately after pairing, individuals perform duets with
poor coordination and poor duet code adherence, but both aspects improve
with time. These results indicate that individuals need a learning period
to be able to perform well-coordinated duets that follow a consistent duet
code. We conclude that both duet coordination and duet code adherence are
honest indicators of pair-bond duration.
