421. Notes on the vocalizations of Eastern Mountain Greenbul (Andropadus nigriceps)

In the following we briefly analyze and compare voice of the different races of Eastern Mountain Greenbul (Andropadus nigriceps). 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). A comparison of voice per race based on available recordings illustrated with sonograms: kikuyuensis song
