Description
Summary:Playback experiments were used to investigate the perception of frequency variations in perch coos by collared doves,Streptopelia decaoctoTerritorial males responded more strongly to modulated than to unmodulated coos. This effect was seen whether all three elements of the coo, or just the first element, were modulated. Modulated coos differed from unmodulated coos in two ways, first by an increased average frequency, and second, by the presence of a discrete change in frequency. We show that it was the change in frequency that was responsible for the level of response to modulated coos. The stronger responses to modulated coos are interpreted as a result of the receiver rating the sender as a stronger competitor.
