Song of Olivaceus Woodcreeper (Sittasomus griseicapillus)
24/01/2009, 17h04. Mãe-da-lua private reserve, Itapajé, Ceará, Brazil. h1740. (c) H. Redies.
Sound h1740. Song of Sittasomus griseicapillus reiseri. The vocalization can be divided into an initial part, where the most prominent frequencies are the harmonics (labels "h1" to "h3" in the figure), and a main part, in which the loudest component of the sound is the fundamental (label "f"). This pattern is quite typical for the song of reiseri, though it is often less pronounced, and can also be absent.

A comparison of the sounds of reiseri with the vocalizations of other subspecies of Sittasomus griseicapillus reveals marked differences, suggesting that reiseri could be a full species (Marantz et al. 2003).

Song of Olivaceous Woodcreeper (Sittasomus griseicapillus)
20/05/2008, 06h00. RPPN Mãe-da-lua, Itapajé, Ceará, Brazil. h1750. (c) H. Redies.
Sound h1750. Another song type from (presumably) Olivaceous Woodcreeper. I employed this song in playbacks, and repeatedly heard the Olivaceous Woodcreeper responding, but with a song like h1740. ID not 100% sure.

The two initial notes n1 and n2 seem to also belong to this vocalization.

05/03/2012, 06h48. Mãe-da-lua private reserve, Itapajé, Ceará, Brazil. h1755. (c) H. Redies.
Sound h1755. Calls, similar to the notes of the song, but irregularly spaced. The footsteps of the recordist, trying to approach the calling bird, can also be heard.
28/12/2010, 17h18. Mãe-da-lua private reserve, Itapajé, Ceará, Brazil. h2037. (c) H. Redies.
Sound h2037. Calls of Olivaceous Woodcreeper, recorded at end of afternoon (17h18). Like h1755.
19/01/2012, 05h47. Mãe-da-lua private reserve, Itapajé, Ceará, Brazil. h1748. (c) H. Redies.
Sound h1748. Trill of Olivaceus Woodcreeper, similar to recordings (9), by R. Parrini, and (10), by D. Buzetti, in the Sittasomus griseicapillus account in Minns et al. 2010. The voice of Sittasomus griseicapillus starts about one second after beginning of recording.

It would be interesting to know what the function of this trill is.
