Song pitch indicates body size and correlates with males' response to playback in a songbird

Popis výsledku v původním jazyce

The inverse relationship between body size and vocalization pitch has been described in a number of species. Nevertheless, the existence of size-pitch allometry within any songbird species is surprising due to the small size variation between males, thedeterminate growth and exceptional vocal prowess of the taxon. The phenomenon has been documented in only a few songbird species so far and the consequences of allometry remain unclear in this taxonomic group. In this study, we provide evidence that songspectral features are related to one of the body size components (tarsus length) even in a very small songbird species: the willow warbler, Phylloscopus trochilus. Moreover, the response of territorial males was affected by the pitch asymmetry between the subject and the playback stimulus: the lower-pitched the subject's song in respect to the stimulus the bolder was its response. Our results suggest that willow warbler males may use song pitch to assess the body size of their rivals (i
