摘要

Female song and the significance of duetting in birds remain puzzling, in part because of the limited number of species studied. We investigated duetting behaviour in the tropical boubou in West Africa. Birds produced a diverse song repertoire consisting of solos, duets and trios, with duets being the most conspicuous vocalization. We identified 12 distinct duet types in which tonal and broadband notes were combined by males and females in highly synchronized and temporally precise patterns. Molecular sexing and observations of colour-banded birds revealed that duets were initiated by both sexes, with strict sex-specific roles maintained within the duet. An equal number of duet types was initiated by males and females. Seven of 12 duets were terminated by the male. Male-initiated duets were also more common (89% of total) and were repeated more often, i.e. sung more frequently. Solo singing occurred when partners did not respond and was also used by unpaired birds. Trios were produced by subadult birds joining the duet of a resident pair. The wide variety of contexts in which duets were sung suggests that they serve several functions, including territorial defence and mutual mate guarding.
