Figure 1. The song of Herpetotheres cachinnans can last a couple of minutes. Here, only a small portion of a song is shown, some 13 seconds. Often, a song initially consists of repetitions of one syllable, then of 2 and finally, after a few minutes, of 3 syllables (A-CAU-Ã). In this extract, it actually seems that 2 birds are singing, one with a single syllable (label A), and the other one, a little louder in the recording, with 3 syllables (labels B1, B2, B3).
