The call of the Bluish Flowerpiercer is a series of “high-pitched notes that trails away and is interspersed with squeaky twittering” (Ridgely and Tudor 2009). The vocalization begins with a 2 or 3 higher pitched slow chirps and gradually lowers in pitch and accelerates into a squeaky trill for about 3 to 4 seconds ( The song is transcribed in Hilty (2003) as “eat’tsu-ti’tip-ta-leep’ta-lip’chilp, chee-ep, cheelip’liz’si”. Altogether the vocalization lasts about 7 seconds and is repeated a few times regularly. ( Additional recordings of the Bluish Flowerpiercer can be found at the Macaulay Library ( or Xeno Canto (
