63. Notes on the vocalizations of Wing-banded Antbird (Myrmornis torquata)

In the following we briefly analyze and compare voice of the two races of Wing-banded Antbird (Myrmornis torquata). We also try to quantify the extent of any vocal differences using the criteria proposed by Tobias et al. (2010), as a support for taxonomic review. We have made use of sound recordings available on-line from Xeno Canto (XC) and Macaulay Library (ML). The song, a rising and slightly accelerating series of loud notes, is quite variable in duration, pace and number of notes, even within every region. It is unclear whether this is mainly induced by playback or not. There are however some characters which allow to distinguish birds from the four main regions as grouped in the following and illustrated in Fig. 1:
