The Common Myna (Acridotheres tristis) and the White-vented Myna (A. javanicus) are the most abundant and widely distributed invasive starlings in Taiwan, having been present on the main island for over 40 years. This study aimed to compare the songs of these two invasive species in sympatric populations in western Taiwan to assess whether song divergence or convergence occurs in this secondary contact zone within the introduced range. We recorded 632 songs from five sites in western Taiwan and analyzed them using principal component analysis (PCA) based on 10 acoustic measurements. The first two principal components (PC1 and PC2) explained 80.6% of the total variation. The PC1 vs. PC2 plot, derived from the acoustic measurements, revealed overlapping groupings between the two species, both in pooled samples from all sites and within individual sites. Further analysis of song recordings from allopatric populations is needed to confirm whether song convergence occurs between these two related species in their invasive range.
