274. Notes on the vocalizations of Grey-cheeked Fulvetta (Alcippe morrisonia)

In the following we briefly analyze and compare voice of the different races of Grey-cheeked Fulvetta (Alcippe morrisonia). 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). Song consists of a short whistled phrase, often followed by some nasal notes.
