141. Notes on the vocalizations of Golden-crowned Flycatcher (Myiodynastes chrysocephalus) and Golden-bellied Flycatcher (Myiodynastes hemichrysus)

In the following we briefly analyze and compare voice of the different races of Golden-crowned Flycatcher (Myiodynastes chrysocephalus) and Golden-bellied Flycatcher (Myiodynastes hemichrysus). 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).
