The population size of green peafowl (Pavo muticus L.) has declined dramatically in Thailand. It is currently found in two geographically isolated regions in the northern and western areas. Here, we assessed the level of genetic variation of this endangered bird species to examine the influence of habitat fragmentation. We collected moulted feather and egg specimens of wild individuals from three populations in the North: Wiang Lor Wildlife Sanctuary (WLO-1 and WLO-2) and Tappaya Lor Non-Hunting Area (TPL). Mitochondrial control region sequences were obtained and analyzed. The results revealed that P. muticus in all populations showed a high level of haplotype diversity (0.784, n = 72), implying high genetic diversity. The haplotype diversity in WLO-1 population was higher than in other two populations. On phylogenetic trees and a haplotype network, the haplotypes of P. muticus individuals did not form a separate cluster, regardless of their distribution ranges, and three haplotypes were found in the three populations. By combining the present results with the previous data, our genetic investigations revealed that P. muticus populations in Thailand exhibited a low genetic difference (4.31%) between the two regional populations with no statistical significance. This suggests that there is no subdivision of wild populations.
