Song of Gray-pileated Finch (Coryphospingus pileatus)
06/06/2006, 05h18. Fazenda Canaã, Pentecoste, Ceará, Brazil. h1811. (c) H. Redies.
Sound h1811. Song sequence of Gray-pileated Finch. In this particular recording, there are six songs (or phrases), each consisting of a series of notes of two types (labels A and B above), which alternate. The sonogram shows the first four notes of the first song.

Within limits, the song is variable. There can be three types of notes, instead of two, and the notes can be different (example: h1810). However, the structure is always similar: a series of notes of a very few basic types, that alternate in a rather monotonous way.

Background species: Spot-backed Puffbird Nystalus maculatus, and others. The sound was bandpass filtered (1200-16000 Hz, sinc filter, sox V14.3.2).

27/04/2008, 06h25. Mãe-da-lua reserve, Itapajá, Ceará, Brazil. h1810. (c) H. Redies.
Sound h1810. Another song sequence of Gray-pileated Finch. In this example, three alternating notes can be heard.

Also: Bananaquit Coereba flaveola, Yellow-breasted Flycatcher Tolmomyias flaviventris, and others. The sound was bandpass filtered (1200-12000 Hz, sinc filter, sox V14.3.2).

Song of Gray-pileated Finch (Coryphospingus pileatus)
19/05/2008, 06h40. Mãe-da-lua reserve, Itapajé, Ceará, Brazil. h282. (c) H. Redies.
Sound h282. Three calls of Gray-pileated Finch. (A) The sonogram shows the second call, at 6.5 s into the recording. (B) This is the waveform of the first 5 milliseconds of the call shown in (A). The sound is amplitude modulated, though the modulation is not always as neat as in this example.

The signal was bandpass filtered (4000-16000 Hz, sinc filter, sox V14.3.2).

Song of Gray-pileated Finch (Coryphospingus pileatus)
29/01/2009, 05h37. Mãe-da-lua reserve, Itapajé, Ceará, Brazil. h287. (c) H. Redies.
Sound h287. Series of calls of Gray-pileated Finch. The sonogram shows one of these calls, with the same time scale as the sonogram of h282. There is a clear difference in duration, shape and delivery rate between the calls of the two recordings, and I suppose that they have different functions. The sound here is possibly a contact call.

The signal was bandpass filtered (4000-16000 Hz, sinc filter, sox V14.3.2).

Song of Gray-pileated Finch (Coryphospingus pileatus)
04/11/2007, 08h04. Mãe-da-lua reserve, Itapajé, Ceará, Brazil. h300. (c) H. Redies.
Sound h300. Another sound of the Gray-pileated Finch, which can be heard quite often. I am not sure about its function.

Background: White-naped Jay Cyanocorax cyanopogon, White-browed Guan Penelope jacucaca. The low-frequency call labeled "Pj" is from a guan.
