440. Notes on the vocalizations of Black-cowled Saltator (Saltator nigriceps)

In the following we briefly analyze and compare voice of Black-cowled Saltator (Saltator nigriceps) with the different races of Golden-billed Saltator (Saltator aurantiirostris). 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).
