SONGS
Both males and females sing. Males often sing 9-11 times per minute during breeding season. Songs are a long, jumbled bubbling introduced by abrupt churrs and scolds and made up of 12-16 recognizable syllables. Females sing mainly in answer to their mates shortly after pairing up; their songs can include high-pitched squeals unlike any sounds males make.
