Song is fast consecutive tingling of high notes with an estimated length of two to four seconds per song (Jaramillo 2003). The song may be divided into segments each song is the almost the same pattern with slight variation “ tchip tchip fui fui tchip tchip” folllowed by notes in quick succession and a pause in between the songs. Intervals are uneven in length, but commonly between ten second to twenty second (Isler and Isler 1987). When intervals are short, thin barely audible moderate-pitched notes are given at a rate of ten to fifteen notes per second (Isler and Isler 1987).
