Pallas\u2019s Leaf Warbler Phylloscopus proregulus is a migratory bird that breeds across mountainous forests from southern\nSiberia to the Far East of northern Asia. However, to date, studies on the songs of this species have been limited to the western area of their\nbreeding range. Here, we document song differences among Pallas\u2019s Leaf Warbler populations across north-east Asia. The population in\nthe Mongolia\u2013Baikal region exhibited significant differences in its acoustic properties from the populations of the Amur River basin and\nSouth Korea. On the other hand, the songs of the Amur River basin and South Korea were not different from each other. Considering the\nforest connectivity between the Amur River basin and Korean peninsula, our findings suggest population structure in Pallas\u2019s Leaf Warblers\nbetween the Mongolia\u2013Baikal region and the Amur\u2013Korea region. To better understand the relationships between these two populations,\na combination of bioacoustic and population-genetic studies coupled with migratory monitoring is recommended.","type_name":"Journal Article","journal_abbreviation":null,"pmid":null,"info_url":"https:\/\/bio.acousti.ca\/node\/58470"}]}
