Annam Limestone Babbler

The Annam limestone babbler (Gypsophila annamensis), also known as the khướu đá hoa in Vietnamese, is a species of bird in the family Pellorneidae. It is native to the limestone hills of northern Indochina. It was formerly considered a subspecies of the variable limestone babbler (G. crispifrons) but a 2020 study recovered it as a distinct species. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. (Wikipedia, general species account).

The accessible general account establishes the species identity, distribution and the natural-history points stated above. Behaviour, diet and breeding can vary geographically, and the available source does not support adding precise Vietnam-specific measurements or nesting dates. This profile therefore retains only species-wide information that can be stated defensibly, rather than filling gaps with unsupported local claims (Wikipedia, general species account).
