359. Notes on the vocalizations of Common Bush-tanager (Chlorospingus ophthalmicus)

In the following we briefly analyze and compare voice of the different races of Common Bush-tanager (Chlorospingus ophthalmicus). 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). With 26 subspecies this is clearly a very complex case.
