Annam Limestone Babbler

The Annam limestone babbler (Vietnamese: khướu đá hoa) is a babbler of the family Pellorneidae native to the limestone hills of northern Indochina. It was formerly treated as a subspecies of the variable limestone babbler but a 2020 study recovered it as a distinct species. Its natural habitats are subtropical or tropical moist lowland and montane forest. The source does not describe its status in China. (Wikipedia, general species account)
