Form and Function Predict Acoustic Transmission Properties of the Songs of Male and Female Canyon Wrens

To function effectively, animal signals must transmit through the environment to receivers, and signal transmission properties depend on signal form. Here we investigated how the transmission of multiple parts of a well-studied signal, bird song, varies between males and females of one species. We h...
