Topic: whistle syllables

Nightingales are renowned for their large song repertoire, including the acoustically distinct type of so-called whistle songs. These contain temporal sequences of unmodulated tonal syllables, known as whistle syllables, defining the fundamental frequency of the song, i.e., the pitch. While recent research has shown nightingales’ ability to adjust acoustic structure to match pitch, the flexibility of their temporal structure remains unexplored. Here, we show that nightingales exhibit a consistent rhythmic pattern in their whistle songs, with a shift in pitch distribution toward lower frequenci
