The communicative significance of song frequency and song length in territorial chiffchaffs

Popis výsledku v původním jazyce

Spectral and temporal measures of vocalizations have been found to correlate with physical parameters that affect the fighting ability in various species of frogs, mammals, and birds. This correlation could play a role in communication for intersexual mate attraction, as well as intrasexual competition. In this study, we investigated whether the frequency and length of territorial songs reflects the body size (tarsus length, weight) of males in a small passerine species, the chiffchaff Phylloscopus collybita. We found a tendency for a negative correlation between song frequency and tarsus length, but no significant links with song length. Furthermore, we carried out playback experiments to see whether the variation in song frequency and length is meaningful to receiving males and found that both parameters affected the males' responses. We found that the response strength was related to the frequency difference between the songs of the tested male and the playback stimulus, rather than
