Taxonomic Swap 116273 (Guardado el 01/11/2022)

Genetic divergence (as measured by mitochondrial DNA; Reddy 2008) is low between Himalayan Shrike-Babbler Pteruthius ripleyi, Blyth's Shrike-Babbler Pteruthius aeralatus, and Dalat Shrike-Babbler Pteruthius annamensis, and plumage differences between most of these also are few and subtle (Rheindt and Eaton 2009). Separation into three species has been justified on the basis of vocal differences (Rheindt and Eaton 2009), but a more recent analysis suggests that vocalizations may be less consistently different than previously thought (Boesman 2016n). Therefore all three species are lumped as White-browed Shrike-Babbler Pteruthius aeralatus. We continue to recognize each of the three previously recognized species as groups: monotypic groups White-browed Shrike-Babbler (Himalayan) Pteruthius aeralatus ripleyi and White-browed Shrike-Babbler (Dalat) Pteruthius aeralatus annamensis, and a polytypic group White-browed Shrike-Babbler (Blyth's) Pteruthius aeralatus [aeralatus Group], with subspecies aeralatus, schauenseei, cameranoi, and robinsoni. The former Blyth's Shrike-Babbler also included two additional monotypic groups: change the English name of the group Pteruthius aeralatus validirostris from Blyth's Shrike-Babbler (Chestnut-winged) to White-browed Shrike-Babbler (Chestnut-winged), and of the group Pteruthius aeralatus ricketti from Blyth's Shrike-Babbler (Gray-breasted) to White-browed Shrike-Babbler (Gray-breasted).
