The warbler is named limestone warbler (Phylloscopus calciatilis), which lives mainly in the forested areas of the limestone mountain area between the Vietnam-Laos border.

In fact, they have been discovered since 1994 but are mistaken for the main yellow-breasted warbler that lives in China 1,000 km away. Recently, scientists have analyzed their morphology, DNA as well as their song and confirmed this is a completely new warbler. This species of warbler has short wings, rounded wings, a wide beak that is proportional to the song and how to call each other completely differently.
