An analysis of songs from 1000+ passerine species shows that peak amplitude usually occurs near the middle of a species’ frequency range. Species with unusually high song frequencies evolved traits that help offset size-based vocal constraints.

The evolution of extreme sound frequencies in bird songs
Abstract. Bird songs differ widely among species and can show peculiar phenotypes, such as extreme or unusual sound frequencies for a species’ body size. A
