Avian duetting is an unusual but taxonomically widespread phenomenon, occurring in over
400 species, representing 40% of bird families. Duets vary in form from loosely overlapping …

Mated birds of many species vocalize together, producing duets. Duetting behavior occurs at
two levels of organization: the individual level and the pair level. Individuals initiate …

Homeothermic animals (birds and mammals) are prime model systems for investigating the
developmental plasticity and neural mechanisms of vocal duetting, a cooperative acoustic …

Duetting is a collective behavior and might have multiple functions, including joint territory
defense and mate guarding. An important step toward understanding the adaptive function …

Duetting has been intensively studied, but we still have little consensus about its fitness
consequences. Some studies suggest that duetting functions in acoustic mate guarding to …

Duets in breeding pairs may reflect a situation of conflict, whereby an individual answers its
partner's song as a form of unilateral acoustic mate guarding or, alternatively, it may reflect …

Vocal individuality is essential for social discrimination but has been poorly studied in
animals that produce communal signals (duets or choruses). Song overlapping and …

Highlights•Rufous horneros were exposed to playbacks of duets varying in temporal
coordination.•Coordinated duets provoked the weakest response from birds.•However …

Duets are a form of poorly understood signal created by two individuals temporally
coordinating their vocalizations. It has been hypothesized that duetting functions in (1) joint …

In this work we study the generation of respiratory patterns by oscine birds. We present a
model capable of generating realistic respiratory patterns, during normal respiration and …
