Antiphonal duets have often been regarded as playing a key role for pairbond maintenance in many tropical songbird species. To test this in the robin chat (Cossypha heuglini) we impaired the exchange of vocal signals between mated individuals by (1) modification of a male's vocal outputs (hypoglossus sectioning), or (2) climination of a female's auditory inputs (deafening). Results showed that auditory signals are not crucial prerequisites for the maintenance of pair bonds, but may well affect a pair's reproductive behaviour.
